TW200807055A - Static progressive surface region in optical communication with a dynamic optic - Google Patents

Abstract

An ophthalmic lens is presented in which the lens includes a progressive addition region and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which is less than a user's near viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise are reduced significantly.

Description

200807055 IX. DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to multifocal ophthalmic lenses, lens designs, lens systems, and eyewear products or devices that are utilized on, in or around the eye. More particularly, the present invention relates to multifocal ophthalmic lenses, lens designs, lens systems, and eyewear products that provide for reducing, in most cases, unwanted distortion associated with enhanced lenses, unwanted astigmatism, and visual impairment to the wearer. A fully acceptable range of optical effects / end results. [Prior Art] The old lb eye is often accompanied by the modulating loss of the lens of the aging person. This accommodative loss results in the inability to focus on close objects. The standard tool for correcting presbyopia is a multifocal ophthalmic lens. A multifocal lens is a lens that has more than one focal length (i.e., power) for correcting focus problems over a range of distances. Multifocal ophthalmic lenses work by dividing the lens area into regions of different power. Typically, a relatively large area located above the lens corrects for remote vision errors, if any. The smaller area at the bottom of the lens provides additional power for correcting near vision errors caused by presbyopia. The multifocal lens may also contain a smaller area located near the middle of the lens, which provides additional power for correcting the mid-range vision error. The transition between regions of different powers can be abrupt (as in the case of bifocal and bifocal lenses), or gentle and continuous (as in the case of enhanced lenses). The enhanced lens is a type of multifocal lens that includes a gradient of positive refractive power that continues to increase from the distance viewing zone of the lens to the close viewing zone of the lower portion of the lens. This increase in power generally begins with the so-called mating cross or mating point of the lens and continues to increase until the full add power is achieved in the close viewing zone and then reaches a plateau. Conventional and current state of the art lenses utilize shaped surfaces formed on one or both of the lenses to form the enhanced power of the power. Promotional lenses are referred to as PAL in the optical industry (plural form is PALs or singular form is PAL). PAL lenses are superior to conventional bifocal and trifocal lenses in that they provide a flawless, cosmetically pleasing multifocal lens to the user when focusing on objects at a distance to close objects or when focusing on It has continuous vision correction when the object is close to the object at a distance. Although PAL is now widely accepted and popular in the United States and throughout the world as a correction for presbyopia, it also has severe visual impairment. Such damage includes, but is not limited to, unwanted astigmatism, distortion, and perceptual blurring. Such visual impairment can affect the horizontal viewing width of the user, which is the field of view width that is clearly seen from side to side when the user is focusing at a given distance. Therefore, when focusing at a medium distance, the PAL lens can have a narrower horizontal viewing width' which makes it difficult to observe a larger portion of the computer screen. Similarly, a PAL lens can have a narrower horizontal viewing width when focusing at close distances. This can make it difficult to view a complete page of a book or newspaper. Long-distance vision can be similarly affected. Due to the distortion of the lens, the pAL lens can also cause difficulties for the wearer while performing sports. In addition, since the optical add power is placed in the bottom area of the APL lens, when the wearer is looking at a close or intermediate distance object above the t head, it must tilt its head backward to use this area. Conversely, 'when the wearer goes down the stairs and assumes downwards, the lens provides a close focus, rather than clearly seeing the long-distance focus necessary for its foot ladder. Because of &, the wearer's feet will be out of focus and the table: blurred. In addition to these limitations, due to the unbalanced distortions that exist in each of the lenses' many PAL wearers experience an uncomfortable experience called visual motion (often referred to as "eyes") effect. In fact, many people refuse to wear these lenses due to this effect. When considering the near-power requirement of presbyopia, the amount of near-power required is directly related to the amount of adjustment (close-range focus) that the individual has in his or her eye. In general, t, as the individual ages, the amount of adjustment is small. The magnitude of the adjustment can also be reduced for various health reasons. Thus, as the individual ages and becomes more presbytic, the power required to correct the person's ability to focus at near and intermediate viewing distances becomes stronger depending on the desired refractive optical add power. For example only, a 45-year-old person may need a near-observation distance power of L00 diopter to see at a near-point distance, while an 80-year-old person may need +2·75 diopters to +3 〇〇 diopters. Observe the distance power to see clearly at the same near point. Since the degree of visual impairment in the PAL lens increases with the refractive power of the refractive optics, a person with a higher degree of presbyopia will experience greater visual impairment. In the above example, a 45 year old would have a lower degree of distortion associated with their lens than a 80 year old. Obviously, considering the life associated with old age (10) quality issues (such as weakness or loss of dexterity), this is exactly the opposite of what is needed. A multifocal lens that adds damage to the vision function and suppresses safety is the opposite of a lens that makes life easier, safer, and less complex. By way of example only, conventional 具有 having a +1 〇〇 D near power [can have a large opaque astigmatism of about 121818.doc 200807055 or about +1.00D or less. However, conventional PALs with +2.50D near-power can have unwanted astigmatism of about +2.75D or more, while conventional PALs with +3.25D near-point power can have about +3.75D or more. Useless astigmatism. Thus, as the PAL gains an increase in close proximity (e.g., +2.50 D PAL compared to + 1.00 D PAL), the unwanted astigmatism found within the pAL increases at a rate greater than the linear rate relative to the close distance. Recently, two-sided PALs have been developed which have an enhanced surface configuration placed on each side of the lens. The two enhanced surfaces are aligned and rotated relative to each other not only provides the appropriate total added close-in addition power required, but also the unwanted astigmatism formed by pal on one surface of the lens and the other by the pal in the lens Some of the unwanted astigmatism formed on the surface is offset by some unwanted astigmatism. Even if this does not reduce the useless astigmatism and distortion of a given close-range add power compared to a conventional PAL lens, the degree of unwanted astigmatism, distortion, and other visual impairments listed above is still severe for the wearer. Vision problems. Therefore, there is an urgent need to provide a vanity need to satisfy the presbyopia and at the same time to correct distortions and blurring while exercising, operating computers and reading books or newspapers, widening the viewing width, allowing improved safety and allowing improved visual ability. Its presbyopic spectacle lenses and / or glasses system. SUMMARY OF THE INVENTION In one embodiment of the invention, an ophthalmic lens having a mating point for a user can include a promotional region having a channel, wherein the enhancing region has an added power. The ophthalmic lens can further include a dynamic optics that can be optically transmitted with an enhanced area having a power at startup. In one embodiment of the invention, a mating point is provided for a user. 121818.doc 200807055 The lens can include a raised area having a channel, wherein the boosting area has/with added power. The ophthalmic lens can further include a dynamic optics that optically transmits upon activation with a region of enhanced power having a top peripheral edge within about 15 mm of the mating point. [Embodiment] Many ophthalmology, optometry and optical terms are used in this application. For the sake of clarity, the definitions are listed below: Adding the power added to the optical power i of the far-sighted power, which is the power required to see at a close distance in the multifocal lens. For example, if an individual has a long-range observation prescription of -3.00D and a close-up observation of +2 〇〇D, the actual power in the close-range portion of the multifocal lens is .00D. Adding power is sometimes referred to as positive power. The addition of power can be further referred to by the "close-to-view distance plus power" (which refers to the added power in the near-observation distance portion of the lens) and the "in-view distance plus the power" (which refers to the lens) The degree of addition in the distance portion is observed to distinguish. Typically, the medium viewing distance add power is approximately 50 〇/ of the near observation distance. . Therefore, in the above example, the individual will have a distance of +1 〇〇 1) to observe the add power and the actual total power in the distance portion observed in the multifocal lens is -2.00D. Approx.: Within 10% of the staff (including 10% of the soil). Therefore, the phrase "about 1 〇 mm, r can be understood to mean from 9 mn^U mm (including 9 111111 and 11 mm). Blending zone: a power conversion along the peripheral edge of the lens, whereby the power is continuously transitioned from the first positive power to the second corrected power on the blending zone or from 121818.doc -10- 200807055 The corrected power continues to transition to the first corrected power. In general, the blending zone is designed to have as small a width as possible. The peripheral edge of the dynamic optics can include a blending zone to reduce the visibility of dynamic optics. The use of blending zones is due to the enhancement of the US Valley and also to enhance visual function. Due to the southern unwanted astigmatism of the blending zone, it is generally not considered a usable part of the lens. The blending zone is also referred to as the transition zone. Channel: A region of the enhanced lens defined by increasing the positive power, the self-traveling power range or region extending to the close power region or region. This power enhancement begins at the area of the PAL referred to as the mating point and ends at the close viewing area. Channels are sometimes referred to as aisles. Channel length: The channel length is the distance measured from the mating point to the position where the added power in the channel is within approximately 85% of the specified close-range viewing power. Channel Width: The narrowest portion of the channel defined by unwanted astigmatism above about +1.00D. This definition is available when comparing PAL lenses due to the fact that wider channel widths are generally associated with less distortion, better visual performance, increased visual comfort, and easier adaptability of the wearer. Contours: Self-measurement and plotting the curves produced by the unwanted astigmatic power of the lens. Contour maps can produce a variety of astigmatic power sensitivities, thus providing a visual map of where and to what extent the lens has unwanted astigmatism as part of its optical design. The analysis of these figures is typically used to quantify PAL channel length, channel width, read width, and wide range yield. The contour map can also be referred to as a astigmatic astigmatism map. These figures can also use _I_ and the power drawn in the various parts of the lens. Conventional channel length: An aesthetic approach or trend due to the style of the eyewear. 121818.doc • 11 · 200807055 A lens with a vertical shortening is required. In this lens, the passage is naturally shorter. 1 Knowing the channel length refers to the length of the channel in the non-shortened PAL lens. These channel lengths are usually (but not always) about 15 mm or longer. In general, a longer channel length means a wider channel width and less unwanted astigmatism. Longer channel designs are often associated with "soft" enhancements because the transition between distance correction and close distance correction is softer due to the slower increase in power. Dynamic lens: - Spectral power can be used A lens that changes with the application of electrical energy, mechanical energy, or force. The entire lens may have a variable power, or only a portion-area or region of the lens may have a variable power. The power of the lens is Dynamic or adjustable 'allows the power to be switched between two or more powers. Among these powers, the power can be substantially absorptive. Dynamic lens Examples include electroactive lenses, meniscus lenses, fluid lenses, movable dynamic optics with or without multiple components, gas lenses, and thin film lenses with deformable components. Dynamic lenses may also be referred to as dynamic optics, dynamic optics. , dynamic optics zone or dynamic optics zone. Remote reference point: a reference point located approximately 3 to 4 _ above the mating cross. Here, the far-distance prescription or long-range power of the lens can be easily measured. The area containing the lens that allows the user to view the power of the power at a distance from the distance. The long-distance width: the narrowest horizontal width in the long-distance observation portion of the lens 〃 provides / month, basically no distortion Correction, and the power is within 0.25D of the long-distance viewing power correction of 121818.doc 12 200807055. Far viewing distance: For example, when someone exceeds the edge of their table to observe 'drive the car When you watch a distant mountain or watch a movie, the distance it sees. This distance is usually (but not always) considered to be about mile or more from the eye. The far viewing distance can also be called far and far. Distance point. Matching cross/fit point: A reference point on the PAL that indicates the approximate position of the pupil when the lens is mounted in the eyeglass frame and positioned on the wearer's face when the wearer looks through the lens. The points are usually (but not always) 2 to 5 mm vertically above the beginning of the channel. The mating cross typically has a very small amount of positive power ranging from slightly above +0·00 diopters to about +012 diopters. This point or cross is marked on the surface of the lens such that it provides a simple reference point for measuring and/or recombining the lens relative to the wearer's pupil. It is easy to assign the lens to the patient/wearer. Ground removal of the mark. Hard enhancement lens · A slower, steeper transition between the distance correction and the close distance correction. In hard PAL, unwanted distortion can be below the fit point and not scale out Within the perimeter of the lens, the hard pAL can also have a shorter channel length and a narrower channel width. A "modified hard enhancement lens" is a hard PAL modified to have a finite number of soft PAL features, Such as slower power transitions, longer channels, wider channels, more unwanted astigmatism extending into the perimeter of the lens, and less unwanted astigmatism below the fit point. Medium distance observation zone: A portion containing a lens that allows the user to observe the distance of the power of the viewing angle. 1218IS.doc -13· 200807055 Observed distance··For example only, when someone reads a newspaper, when they operate the computer, when they brush the dishes in the sink, or when they iron the clothes, they see the distance. This distance is usually (but not always) considered to be between about 16 inches and about 32 inches from the eye. The medium viewing distance can also be referred to as the medium distance and the medium distance. Lens: Any part of a device or device that converges or diverges light. The device can be static or dynamic. The lens can be refracting or diffractive. The lens may be concave, convex or flat on one or both surfaces. The lens can be spherical, cylindrical, prismatic or a combination thereof. The lens can be made of optical glass, plastic or resin. A lens can also be referred to as an optical element, an optical zone, an optical zone, a power zone, or an optics. It should be noted that in the optical industry, a lens can be referred to as a lens even if it has zero power. Lens blank: A device made of an optical material that can be shaped into a lens. The lens can be trimmed to mean that the lens strands are shaped to have power on both outer surfaces. The fact that the lens blank can be half-finished means that the lens blank is shaped to have power on only one outer surface. The fact that the lens blank may not be trimmed means that the lens blank may not be shaped to have power on either outer surface. The surface of the unfinished or semi-trimmed lens blank can be trimmed by a process known as freeform or by more conventional surface processing and grinding. Low add power PAL - A type of enhanced lens with a near add power that is less than the wearer's near-added power at close range. Multifocal lens: A lens having more than one focus i-focus I. The lenses can be static or dynamic. Examples of static multifocal lenses include bifocal lenses, trifocal lenses, or promotional lenses. Examples of dynamic multifocal lenses 121818.doc -14-200807055 include electroactive lenses whereby various optical powers are formed in the lens depending on the type of electrode used, the voltage applied to the electrodes, and the refractive index that changes within the thin layer of liquid crystal. Multifocal lenses can also be a combination of static and dynamic. For example, an electroactive element can be used for optical transmission with a static spherical lens, a static single light lens, a static multifocal lens such as, for example, a promotional lens. In most cases (but not all cases), the multifocal lens is a refractive lens.

Close-range viewing area: A portion containing a lens that allows the user to view the power of the power at a near viewing distance. Near viewing distance: For example, when someone is reading a book, when they are wearing a needle, or when reading the instructions on the vial, the distance they see. This distance is usually (but not always) considered to be between about 12 inches and about 16 inches from the eye. The near viewing distance can also be referred to as a close distance and a close distance point. Office lens/office pal · A specially designed promotional lens that provides mid-range vision above the cross, wider channel width, and wider read width. This is achieved by an optical design that expands unwanted astigmatism above the mating cross and that replaces the far vision zone with a field of vision that is primarily a mid-range vision zone. Due to these characteristics, this type of PAL is particularly suitable for departmental work, but since the lens does not contain a remote viewing area, the wearer cannot use this type of PAL while driving or walking around the office or home. Ophthalmic lens: A type of frogscope that is suitable for vision correction, including spectacle lenses, contact lenses, intraocular lenses, corneal inlays, and keratoplasts.

A pad electrode: an electrode utilized in an electroactive lens that allows the refractive power formed by the liquid crystal to be diffracted by applying an appropriate voltage to the electrode regardless of the size, shape, and configuration of the electrode. For example, a diffractive optical effect can be dynamically generated within a liquid crystal by using a concentric ring electrode. Pixelated electrode: An electrode utilized in an electroactive lens that can be individually addressed regardless of the size, shape, and configuration of the electrodes. Furthermore, since the electrodes can be individually addressed, any random mode voltage can be applied to the electrodes. For example, the pixelated electrodes can be squares or rectangles arranged in a Cartesian array or hexagons arranged in a hexagonal array. The pixelated electrodes need not be in a regular shape that conforms to the grid. For example, if each ring is individually addressable, the pixelated electrodes can be concentric rings. The concentric pixelated electrodes can be individually addressed to form a diffractive optical effect. Enhancement region: a lens region having a first power in a first portion of the region and a second power in a second portion of the region, wherein there is a continuity between the first portion and the second portion The power of the power changes. For example, a region of the lens may have a far viewing distance at one end of the region. The power can be continuously increased in positive power on the area to a medium viewing distance power and a near viewing distance power to the opposite end of the area. After the power reaches the near-observation distance power, the power can be reduced in such a way that the power of the enhanced region transitions back into the far-view distance. The enhancement zone can be on the surface of the lens or embedded in the lens. When the enhancement zone is on the surface and contains a surface configuration, it is referred to as a promotional surface. 121818.doc -16 - 200807055 Read Width: The narrowest horizontal width in the close-up portion of the lens, which provides a clear, virtually distortion-free correction' and the power is corrected by the wearer at close range. Within 0.25D. Short channel length: Due to the aesthetic relationship or trend of the style of the glasses, a lens with a vertical shortening may be required. In this lens, the passage is naturally shorter. The short channel length refers to the length of the channel in the shortened PAL lens. These channel lengths are usually (but not always) between about 11 mm and about 15 mm. In general, a shorter channel length means a narrower channel width and more astigmatism. Shorter channel designs are often associated with "hard n enhancements because the transition between remote and close correction is harder due to a steeper increase in power. Soft enhancement lens: A progressive lens with a slower transition between long range correction and close distance correction. In soft PAL, unwanted distortion can be spread over the mating point and outward into the perimeter of the lens. Soft PALs can also have longer channel lengths and wider channel widths. A ''modified soft enhancement lens, a soft PAL modified to have a finite number of hard PAL features, such as ® steeper power transitions, shorter channels, narrower channels, more The unwanted astigmatism advances into the lens viewing portion, and more unwanted astigmatism is below the mating point. Static lens: A lens that has a power that cannot be changed with the application of electrical energy, mechanical energy, or force. Examples of static lenses include spherical lenses, cylindrical lenses, promotional lenses, bifocal lenses, and trifocal lenses. Static lenses can also be referred to as fixed lenses. Useless astigmatism: Improves the useless aberrations, distortions, or distractions found in the lens. 121818.doc •17· 200807055 Light 'It does not specify the part of the vision correction for the patient, but is inherent in the optical design of the P AL, due to A gentle gradient of power between the observation zones. Although the lens can have unwanted astigmatism over different regions of the various diopter lenses, the unwanted astigmatism in the lens generally refers to the largest unwanted astigmatism found in the lens. Useless astigmatism can also refer to unwanted astigmatism located in a particular portion of the lens (as opposed to the entire lens). In this case, a quantization language is used to indicate that only unwanted astigmatism within a particular portion of the lens is considered. When describing dynamic lenses, the present invention encompasses, by way of example only, electroactive lenses, fluid lenses, gas lenses, film lenses, and mechanically movable lenses. Examples of such lenses can be found in U.S. Patent Nos. 6,517, 2035 to Blum et al., U.S. Patent Nos. 6,491,394, 6,619,799, Epstein and Kiirtin, U.S. Patent Nos. 7,008,054, 6,040,947, 5,668,620, 5,999,328. No. 5,956,183, 6,893,124, U.S. Patent Nos. 4,890,903, 6, 6, 69,742, 7,085,065, 6,188,525, 6, 618, 208, Stoner, U.S. Patent No. 5, U.S. Patent No. 5,229,885 to Qua. It is well known and accepted in the optical industry that the user of the lens (in most cases) is difficult to perceive as long as the unwanted astigmatism and distortion of the lens is at about 1.00 D or less. The invention disclosed herein relates to embodiments of optical design, lens and eyeglass systems that address many, if not most, of the problems associated with P AL. Additionally, the invention disclosed herein significantly excludes most of the visual impairment associated with PAL. The present invention provides a means for achieving the appropriate far, medium and close power of the wearer, while providing a continuous focusing capability for various distances, similar to the focusing power of PAL, 121818.doc -18-200807055. However, for certain high add powers such as +3.00D, +3.25D, and +3_5〇D, the present invention simultaneously maintains unwanted astigmatism to a maximum of about 15 〇D. However, in most cases, the present invention maintains unwanted astigmatism to a maximum of about 1.00 D or less. The present invention is based on aligning the low add power PAL with the dynamic lens such that the dynamic lens is optically transmitted with the low add power PAL, whereby the dynamic lens provides the wearer with a clear view of the additional required power at close range. This combination produces unexpected results: not only can the wearer see the mid-range and close-up, but the degree of unwanted astigmatism, distortion, and visual impairment is significantly reduced. The dynamic lens can be an electroactive element. In an electroactive lens, electroactive light is embedded in or attached to the surface of the optical substrate. The optical substrate can be a trimmed, semi-trimmed or unfinished lens blank. When a semi-trimmed or untrimmed blank is used, the lens blank can be trimmed during the manufacture of the lens to have one or a single power. Electroactive optics can also be embedded in or attached to the surface of conventional optical lenses. Conventional optical lenses can be single focus lenses or multifocal lenses, such as promotional lenses or bifocal or trifocal lenses. The electroactive optics can be located throughout the viewing area of the electroactive lens or in only one of it. Electroactive optics can be spaced from the peripheral edge of the optical substrate to educe the electroactive lens into spectacles. The electroactive element can be located near the top, middle or bottom of the lens. When substantially no voltage is applied, the electroactive optics can be in a disabled state, wherein it generally does not provide power. In other words, when substantially no voltage is applied, the electroactive optics can have the same refractive index as the optical substrate or the conventional lens in which it is embedded or attached to 121818.doc -19-200807055. When a voltage is applied, the electroactive optics can be in a state of turbulence that provides him with the added power of the nine. In other words, when electrical waste is applied, the electroactive optics can have a refractive index that is different from that of an optical substrate or a conventional lens that is aged or attached. Electroactive lenses can be used to correct for conventional or non-conventional errors in the eye. This correction can be formed by an electroactive element, an optical substrate or a conventional optical lens or by a combination of the two. Eye misunderstandings include low-order aberrations such as myopia, hyperopia, presbyopia, and astigmatism. Non-fognitive errors in the eye include higher order aberrations, which can be caused by eye layer irregularities. - Liquid crystal can be used as part of electroactive optics because the refractive index of liquid crystal can be changed by generating an electric field on the liquid crystal. The electric field can be generated by applying one or more voltages to electrodes located on both sides of the liquid crystal. The electrodes can be substantially moon-permeable and fabricated from a substantially transparent conductive material such as indium tin oxide (iridium tin oxide) or other such materials well known in the art. Liquid-based electro-optical optics can be especially suitable for electroactive optics. The & liquid crystal provides a range of refractive index changes to provide an optical add power of flat to +3 〇〇D. This optical add power range may be able to correct the presbyopia of most patients. A thin layer of liquid crystal (less than 10 μm) can be used to construct electroactive optics. The liquid crystal layer can be sandwiched between two transparent substrates. The two substrates may also be sealed along their peripheral edges to seal the liquid crystal within the substrate in a substantially airtight manner. A layer of transparent conductive material can be deposited on the inner surface of two substantially planar transparent substrates. A conductive material can then be used as the electrode. When a thin layer is employed, the shape and size of the electrodes can be used to induce specific optical effects within the lens. The required operating voltage of these electrodes to be applied to the 121818.doc • 20-200807055 liquid crystal layer may be, typically less than 5 volts. The electrode can be patterned by ~ 目田低 π j broken. For example, a diffractive ring effect can be dynamically generated within the crystal using concentric ring electrodes at least in the substrate. The optical effect can be optically additive based on the ring radius, the core width, and the electrical range applied to the different rings, respectively. The electrodes can be pixelated. For example, the pixelated electrodes can be squares or rectangles arranged in a Cartesian array or hexagons arranged in a hexagonal array. The pixelated electrode array

~ 』 used for hunting by the 椟-like diffraction concentric ring electrode structure to produce optical add power. The phlegm electrode can also be used to correct higher order aberrations of the eye in a manner similar to that used to correct atmospheric turbulence in ground-based astronomy. Current manufacturing methods limit the minimum pixel size and also limit the maximum moving electrical active optical diameter. By way of example only, when using a diffraction pattern; the maximum dynamic electroactive optical diameter is estimated to be 20 mm for + 1.50D, 24 _ for +1.25D, and 30 for + ι _ Mm. Current manufacturing methods limit the maximum dynamic electroactive optical diameter when using pixelated diffraction methods. In the same manner, embodiments of the present invention may have dynamic electroactive optics having a smaller power at a larger diameter. Alternatively, the electroactive optics comprise two transparent substrates and a liquid crystal layer, wherein the first substrate is substantially flat and coated with a transparent conductive layer, and the second substrate has a meshed surface having a surface convex and concave diffraction pattern It is also coated with a transparent conductive layer. The surface convex-concave diffractive optics is a solid substrate having a residual or formed diffraction grating on /. The surface relief pattern can be formed by diamond cutting, injection molding, die casting, thermoforming, and stamping. 121818.doc • 21 - 200807055. The optics can be designed to have fixed power and/or aberration correction. By applying electric dust to the liquid crystal via the electrodes, the power/disparity correction can be turned on and off by refractive index mismatch and matching, respectively. The liquid crystal may have substantially the same refractive index as the surface convex-concave diffractive optics when applied substantially without electricity. This cancellation is typically the power provided by the surface convex and concave diffractive elements. The liquid crystal may have a refractive index different from that of the surface convex and concave diffractive elements when a voltage is applied, such that the surface convex and concave diffractive elements now provide optical add power. Dynamic electroactive optics having a larger diameter or horizontal width can be fabricated by using a surface convex and concave diffraction pattern method. The width of these optics can be as high as or greater than 4 〇 mm ° and also use a more liquid crystal layer (usually > 5 〇 μιη) to construct electroactive multifocal point optics. For example, a modal lens can be employed to form refractive optics. It is known in the art to model a lens with a single continuous low conductivity circular electrode that is surrounded by and in electrical contact with a single highly conductive ring electrode. After she applies a single voltage to the 咼 conductive ring electrode, the low-conductivity electrode, the substantially radial symmetrical resistance network creates a voltage gradient across the liquid crystal layer, which then induces a refractive index gradient in the liquid crystal with a refractive index gradient (5) The layer will act as an electroactive lens and will focus the light incident thereon. In the "embodiment of the invention, the combination of dynamic optics and enhancement lenses to form a combination lens 1 into the lens may be a low add power enhancement lens. The promotional lens contains a promotional area. Dynamic optics can be positioned such that it is optically transmitted to the enhanced region.

In an embodiment of the invention, the dynamic optics may have +0.50D, +0.75D, +1.00D, +1.12D, +1.25D, +1.37D, +1.50D, +1.62D, + 1.75 in the startup state. The power of one of D, +2.00D and +2.25D. The add power and dynamic optical power of the enhanced region can be manufactured or specified for patients with a +0.125D (which is approximately +0.12 or +0.13) refractive index or a +0.25D refractive index. It should be noted that the present invention encompasses any and all possible power combinations (dynamic and static) required to properly correct the wearer's vision at the far, middle and near viewing distances. The examples and embodiments of the invention are provided by way of illustration only and are not intended to be limiting. Rather, it is intended to show the add power relationship when the low add power enhancement region is optically transmitted with dynamic optics. Dynamic optics can have a blending zone such that the power along the perimeter edge of the component is blended to reduce the visibility of the peripheral edge when the component is activated. In most, but not all, cases, the power of the dynamic optics can be maximized by the dynamic power of the dynamic optics when freely activated in the blending zone to enhance the power found in the lens. In an embodiment of the invention, the blending zone may be from 1 mm to 4 mm wide along the dynamic optical peripheral edge. In another embodiment of the invention, the blending zone may be 1 mm to 2 mm wide along the dynamic optical peripheral edge. When dynamic optics is disabled, dynamic optics will generally not provide optical add power. Thus, when dynamic optics is disabled, the enhancement lens provides all of the added power of the combined lens (i.e., the total add power of the combined optics is equal to the added power of the PAL). If the dynamic optics include a blending zone, then in the disabled state, 121818.doc -23-200807055 due to index matching in the disabled state, the blending zone generally does not form a power and is substantially free of unwanted astigmatism. In an embodiment of the invention, when the moving optics are disabled, the total unwanted astigmatism in the combined lens is substantially equal to the unwanted astigmatism caused by the progressive lens. In an embodiment of the invention, when dynamic optics is disabled, the combined add power of the combined optics may be approximately +1 〇〇 D and the total unwanted astigmatism within the combined lens may be approximately i. (10) D or less. In another embodiment of the invention, when dynamic optics is disabled, the combined optical, ',' add power may be approximately +1 25D and the total unwanted astigmatism within the combined lens may be approximately 1.25D or less. In another embodiment of the invention, when dynamic optics is disabled, the combined add power of the combined optics may be approximately +1.5 0D and the total unwanted astigmatism within the combined lens may be approximately 15 〇 d or less. When dynamic optical start-up, dynamic optics will provide additional power. Because the L-optical and the enhanced lens are optically transmitted, the total add power of the combined optics is equal to the add power of the PAL and the add power of the dynamic optics. Dynamic optics includes a blending zone, and in the activated state, the blending zone forms power and unwanted astigmatism due to refractive index mismatch in the activated state, and is largely unusable for vision focusing. When dynamic optics includes a blending zone, the unwanted astigmatism of the combined optics is only measured within the available portion of the dynamic optics that does not include the blending zone. In an embodiment of the invention, when dynamic optics is initiated, such as via Measured by the available portion of the lens, the total unwanted astigmatism in the combined lens can be substantially equal to the useless astigmatism within the enhanced lens. In the & examples of the present invention, 'when dynamic optics is activated and combined optical total add power Between about +〇.75D and about +2·25〇, the total unwanted astigmatism in the portion of the combined lens I21818.doc •24-200807055 can be 1.00D or less. Another in the present invention In embodiments, when dynamic optics is activated and the total add power of the combined optics is between about +2.50D and about +2.75D, the total unwanted astigmatism in the available portion of the combined lens can be L25D or less. In another embodiment of the invention, when dynamic optics is initiated and the total add power of the combined optics is between about +3.00D and about +3.50D, the total unwanted astigmatism in the available portion of the combined lens can be 1.50. D or less. Thus, the present invention allows for the formation of a lens having a total additive power that is significantly higher than the unwanted astigmatism of the lens (as measured by the available portion of the lens). Or alternatively, for the present invention Combined lens Total addition of power generally reduces the degree of unwanted astigmatism. This is a significant improvement with respect to lenses or commercially available lenses taught in the literature. This improvement translates to higher fit rates, less distortion, The wearer has fewer errors or misalignments and a wider clear mid-range and close-range field of view as observed by the wearer. In one embodiment of the invention, dynamic optics can form a user's near vision prescription The required total add power is between about 3 〇〇/❶ and about 。. The low add power PAL enhancement area can form the rest of the user's close vision prescription, ie, respectively Between about and about 30. In another embodiment of the invention, the xenon optics and enhancement regions can each form about 50% of the total add power required to prescribe (4) a close vision. The right dynamic optics creates too much total add power, so when the dynamic lens is disabled, the user may not be able to see it at a medium distance. In addition, when the motion = light dry start, the user may have too much power in the mid-range viewing zone and may also not be able to see it at a medium distance. If dynamic optics 121818.doc -25- 200807055 forms too little total added eschar, the combined lens can have excessive unwanted astigmatism. When the dynamic optics include a blending zone, dynamic optics may be required to be wide enough to ensure that at least a portion of the blending zone is in the perimeter of the combined optics. In one embodiment of the invention, the dynamic optics may have a horizontal width of about 26 mm or greater. In other embodiments of the invention, the horizontal width of the dynamic optics may be between about 24 mm and about 4 mm. In another embodiment of the invention, the horizontal width of the dynamic optics is between about 30 mm and about 34 mm. If the moving optics is less than about 24 ga in width, the erbium blending region can create an interface with the user's vision and create excessive distortion to the user and cause dazzling when dynamic optical activation. If the dynamic optics is greater than about 40 mm in width, it may be difficult to sharpen the combined lens into a spectacle frame shape. In most cases (but not in all cases), the dynamic optics may have an elliptical shape when the dynamic optics are positioned such that the blending zone is at the mating point of the combined lens or below the mating point of the combined lens. The width dimension is greater than its 0 vertical height dimension. When the dynamic optics is positioned such that its blending zone is above the mating point, the dynamic optics is typically (but not always) positioned such that the top perimeter edge of the dynamic optics is at least 8 mm above the mating point. It should be noted that non-electroactive dynamic optics can be placed to the peripheral edge of the combined lens. Additionally, the non-electroactive dynamic optics can be less than 2 4 m in width. In an embodiment of the invention, the dynamic optics are located at or above the mating point. The top edge of the dynamic optics can be between approximately 〇 mm and 15 mm above the mating point. Dynamic optics, when activated, provides the power required to be viewed by the wearer at medium distances, close distances, or some distance between the medium and close distances (near _121818.doc -26-200807055 distance) . This is due to the dynamic optics being located at or above the mating point. This will allow the user to have a corrected mid-range prescription when looking directly. In addition, due to the enhanced area, the power continues to increase from the mating point through the passage. When viewed through this channel, the user will have a correction for near-middle distance and close-range prescription corrections. Thus, the user may not need to look down in many situations until or must raise their lower jaw until viewed through the mid-range viewing area of the lens. If the dynamic optics are vertically spaced from the top of the combined lens, the user can also view at a distance by utilizing a portion of the combined lens above the activated dynamic optics. When dynamic optics is disabled, the lens area at or near the mating point will return to the distant power of the lens. In embodiments where the sinister optics have a blending zone, positioning the dynamic optics above the mating point may be preferred. In this embodiment, when dynamic optical activation is enabled, the latter can be made to pass through the mating point and through the channel to look straight down without observing through the blending zone. As mentioned above, the blending zone can introduce a high degree of unwanted astigmatism through which viewing can be uncomfortable. Thus, the user can use the combined optics in the activated state without experiencing a high degree of unwanted astigmatism because the user does not have to cross the edge or blending area of the dynamic optics. In an embodiment of the invention, the dynamic optics are located below the mating point. The top edge of the sorrowful optics can be placed between the melon and the melon below the fit point. When the user is looking directly through the mating point, the remote prescription is provided by the combined optics because the dynamic optics does not optically transmit to this portion of the combined lens. However, when the user shifts their gaze through the channel from the point of fit, the user can experience a high degree of unwanted astigmatism as the user's eyes pass over the dynamic optical blending zone. This can be corrected in a number of ways as described in detail below. The combination ophthalmic lens of the present invention comprises an optical design which considers: 1) the ophthalmic lens of the present invention satisfies the total near-distance addition power required for the wearer's near vision correction; ^ 2) is useless in the usable portion of the combined lens The degree of astigmatism or distortion; • 3) the amount of optical add-on that is partially formed by the enhanced region; 4) the amount of power formed by dynamic optics when activated; _ 5) the length of the channel in the enhanced region; 6) Whether it is (for example only) soft PAL design, hard PAL design, modified soft PAL design or modified hard PAL design enhancement area design; 7) dynamic optics width and length; and 8) dynamic optics relative to enhancement The location of the area. FIG. 1A shows an embodiment of a progressive lens 100 having a mating point 110 and a boosting region 120. The progressive lens of Figure 1A is a low add power enhancement lens, which is designed to provide the wearer with the desired power less than the wearer's required close power power correction. For example, the added power of PAL can be 50% of the proximity power correction. The distance from the mating point along the lens axis AA to the point at which the optical power on the lens is within 85% of the power to be added is referred to as the channel length. The channel length is represented as distance D in Figure 1A. The value of the distance D can vary depending on many factors, such as the frame style (the lens will be edged to conform to the frame), the amount of power required, and the desired channel width. In one embodiment of the invention, the distance D is between about 11 mm and about 20 mm. In another embodiment of the invention, 121818.doc -28 - 200807055, the distance D is between about 14 mm and about i8 mm. Fig. 1B is a graph showing the power of 130 taken along the axis aa of the cross section of the lens. The axis of the graph represents the distance along the central axis aa of the lens. The y-axis of the graph represents the amount of power in the lens. The power shown in the graph begins at the mating point. The power at or before the mating point may be from about +0.00D to about +〇12D (i.e., approximately no optical power) or may have positive or negative diopter as desired by the user's long distance prescription. Figure 1B shows a lens that does not have a power before the mating point or at the mating point. After the mating point, the power continues to increase to the maximum power. For a certain length of the lens along the axis AA, the maximum power can continue to exist. Figure 1B shows that the maximum power persists, which is manifested by the smoothness of the power. Figure 1B also shows the distance D that occurs before the maximum power. After the maximum power steady state, the power can then continue to decrease until the desired power. The desired power may be any power less than the maximum power and may be equal to the power at the mating point. Figure 1B shows that the power is continuously reduced after the maximum power. In one embodiment of the invention, the enhancement region can be a raised surface on the front surface of the lens and the dynamic optics can be embedded within the lens. In another embodiment of the invention, the enhancement region can be an elevation surface on the rear surface of the lens and the dynamic optics can be embedded within the lens. In another embodiment of the invention, the snagging region can be two enhancing surfaces, one of which is on the front surface of the lens and the second surface is on the rear surface of the lens (such as the surface of the dual surface enhancing lens) and is dynamically optically embeddable. Buried inside the lens. In its embodiment of the invention, 121818.doc • 29-200807055, the enhancement region may be produced by a geometric surface, but may be produced by a refractive index gradient. This embodiment will allow the two surfaces of the lens to resemble the surface used on a single focus lens. The refractive index gradient providing the enhancement region can be located inside the lens or on the lens surface. An important advantage of the present invention as described above is that the wearer always has a corrected intermediate distance and a distant visual power even when dynamic optics is in a disabled state. Thus, the only control mechanism that may be required is a component for selectively activating dynamic optics when the wearer requires proper proximity power. This effect is provided by a low add power PAL having an add power that provides a power less than the user's prescription close distance at a close distance, and further, this low add power is close to the wearer The medium distance observation requires correction of the prescription power. When dynamic optics is activated, the wearer's close-range power focusing needs to be met. This greatly simplifies the sensor set required to control the lens. In fact, all that is needed is a sensing device that detects if the user is out of focus and is in focus. Dynamic optics can be activated if the user is focusing closer than a long distance. Dynamic optics can be disabled if the user is not focusing closer than the distance. The device can be a simple tilt switch, manual switch or range finder. In this embodiment, a small amount of transient delay can be placed in the control system I' to allow the patient's eyes to cross the perimeter of the dynamic optics before the dynamic optical activation. This allows the wearer to avoid any annoying useless distortion effects that may be beneficial when the optical includes the blending zone by the observation of the peripheral edge of the sorrowful optics. Only the calf • and "' when the observer's line of sight observes a distant object to - close to 121818.doc • 30- 200807055 When the object moves, the wearer's eyes will turn to the near edge of the dynamic optics Distance to the observation area. In this case, dynamic optics will not start until the wearer's line of sight has crossed the dynamic optical peripheral edge and into the close viewing zone. This occurs by delaying the activation of the dynamic optics to allow the wearer's line of sight to pass over the perimeter edge. If the activation of the dynamic optics is not temporarily delayed and instead is initiated before the wearer's line of sight crosses the peripheral edge, the wearer can experience a high degree of unwanted astigmatism as viewed through the peripheral edge. This embodiment of the invention is typically utilized when the peripheral edge of the dynamic optics is at or below the mating point of the combined lens. In other embodiments of the invention, the peripheral edge of the dynamic optics may be located above the mating point of the combined lens and, therefore, in many cases, the delay may not be needed because the wearer is viewed between mid and close distances. The line of sight never crosses the peripheral edge of the dynamic optics. In other embodiments of the present invention, the dynamic optical enhancement lens and blending region can be designed such that in the region where the two overlap, the unwanted astigmatism in the blending region at least partially offsets some of the unwanted astigmatism in the PAL. some. This effect is comparable to a two-sided PAL where the unwanted astigmatism of one surface is designed to counteract some of the unwanted astigmatism of the other surface. In one embodiment of the invention, it may be desirable to increase the size of the dynamic optics and position the dynamic optics such that the top perimeter edge of the dynamic optics is above the mating point of the lens. 2A shows an embodiment of a low add power enhancement lens 200 in combination with a larger dynamic optics 22 that is placed such that the top perimeter edge 250 of the dynamic optics is above the mating point 21〇 of the lens. In one embodiment of the invention, the larger dynamic optics have a diameter between about 24 1^11 and about 40 mm. Vertical shift of dynamic optics relative to the mating point of the lens 121818.doc •31- 200807055 is represented by the distance d. In one embodiment of the invention, the distance d is in the range of from about 〇mm to about half the diameter of the dynamic optics. In another embodiment of the invention, the distance d is the distance between about one-eighth of the dynamic optics and three-eighths of the diameter of the dynamic optics. 2B shows an embodiment having a combined power 230 that is formed by optical transmission of the dynamic optics and enhancement region 240. Lens 200 can have a reduced channel length. In one embodiment of the invention, the channel length is between about 11 mm and about 20 mm. In another embodiment of the invention, the channel length is between about 14 mm and about 18 mm. In the embodiment of the invention illustrated in Figures 2A and 2B, when dynamic optical activation, the lens has a low add power PAL and dynamic optics are located above the mating point' so the wearer has corrected mid-range vision when looking directly at the eye. As the wearer's eyes move below the channel, the wearer also has a corrected near-to-middle distance. Finally, the wearer has corrected near vision in the area of the combined lens. In the combined lens area, the dynamic optics and the enhanced area are grouped to form the desired near viewing distance correction. This is an advantageous method of combining dynamic optics and enhanced areas because the computer uses primarily the medium-observation distance task and observes the observation distance task in the electric screen for a large number of people viewing in a direct or slightly downward viewing position. In the disabled state, the area of the lens above the mating point and close to the mating point allows for the use of weak gain enhancement below the mating point for distance vision observation correction. The maximum power of the enhanced region forms approximately half of the close power required by the wearer and the dynamic optics form the remainder of the power required for clear near vision. 3A-3C illustrate an embodiment of the invention in which dynamic optics 32 is disposed 121818.doc • 32-200807055 within lens 300 and enhancement region 31 is placed on the rear surface of the lens. This post-enhancement surface can be placed on the lens during processing of a semi-trimmed lens having integrated dynamic optics by a manufacturing process known as freeform. In another embodiment of the invention, the enhancement zone is located on the surface of the semi-trimmed lens blank before the semi-trimmed lens blank and has dynamic optics such that the dynamic optics are properly aligned with the elevation surface curvature. The semi-finished lens fan is then processed by conventional surface processing, grinding, edge grinding, and women's clothing into the eyeglass frame. As illustrated in Figure 3A, when dynamic optics is disabled, the optical power obtained by the wearer's eye 34 透过 through the line of sight of the mating point provides the wearer with corrected distance vision 330. As illustrated in Figure 3B, when dynamic optical activation is initiated, the optical power obtained by the wearer's eye through the line of sight of the mating point provides the wearer with a corrected mid-range focus power 331. As the wearer moves its gaze below the channel (as shown in Figures 3B-3C), the combined optics of the dynamic optics and the enhanced surface provides a substantially continuous power transition from one of the mid-range focus to the close focus. Thus, as illustrated in Figure 3C, upon dynamic optical activation, the wearer is provided with a corrected close focus power 332 along the power taken from the wearer's eye through the line of sight of the close viewing area. A major advantage of this embodiment of the invention may be that the control system only needs to determine if the wearer is looking at a distance. In this case of distance observation, dynamic optics can remain disabled. In an embodiment using a ranging device, the ranging system only needs to determine if the object is closer to the eye than the wearer. In this case, dynamic optics will be activated to provide combined power, allowing simultaneous mid-range and close-range power correction. Another major advantage of this embodiment of the present invention is that when the sinus optical is activated, such as when the user is from the remote portion of the lens 121818.doc -33 - 200807055 to the close portion of the lens and the user from the lens The eye does not need to cross or pass through the upper edge of the dynamic optics when viewed from a close distance portion to a remote portion of the lens. If dynamic optics have its uppermost edge below the fit point, & the eye must cross or pass through the upper edge when viewed from a long distance to a close distance or from a close distance to a long distance. However, embodiments of the present invention may allow the dynamic optics to be positioned below the mating point such that the eye does not cross the uppermost edge of the tamper optical. This embodiment may allow for other advantages regarding visual performance and ergonomics. Although Figures 3A-3C illustrate enhanced surface areas on the back surface, they may also be placed on the front surface of the lens or on the front and back surfaces of the lens when the dynamic optics are within the lens. Further, although the dynamic optics are illustrated as being located inside the lens, they may also be placed on the surface of the lens if they are made of a curved substrate and covered by an ophthalmic cover material. The number of dynamic optical half-trimmed blank SKUs may be substantially reduced by using a dynamic optical having known powers combined with different PAL lenses each having a different added power. For example, +0.75D dynamic optics can be combined with a +0.50D, +0.75D, or +1.00D enhancement region or surface to produce an add power of +125D, +1.50D, or +1.75D, respectively. Or +1.00D dynamic optics can be combined with a +0.75D or +1.00D enhancement region or surface to produce an add power of +1.75 or +2.00D. In addition, the 'enhanced area can be optimized to account for wearer characteristics, such as the patient's long-range power and the eye path through the lens, and the fact that the enhanced area is added to provide dynamic electroactive optics that provide approximately half of the read correction required. . Similarly, the opposite can work well. For example, a +1.〇〇D enhancement region or surface can be combined with +0.75D, +1.00D, +1.25D, or +1.50D dynamic optics 121818.doc -34-200807055 to produce +1.75D, +2.00D Add a power of +2.25D or +2.50D. 4A illustrates another embodiment of the present invention whereby the low add power enhancement lens 400 is combined with dynamic optics 420 that is larger than the enhancement region and/or channel 430. In this embodiment, the unwanted distortion 450 from the dynamic optical blending region is at the mating point 410 and the enhancement channel 430 and the read region 440. 4B-4D are graphs showing the power taken along the axis AA of the lens cross section of Fig. 4A. The X-axis of each graph represents the distance along the central axis AA of the lens. The y-axis of each _ graph represents the amount of power in the lens. The power at or before the mating point may be from about +0.00D to about +0.12D (i.e., approximately no power) or may have positive or negative diopter as desired by the user's long distance prescription. Figure 4B shows a lens that does not have power before the mating point or at the mating point. Figure 4B shows the power 460 provided by the fixed promotional surface or region taken along axis AA of Figure 4A. Figure 4C shows the power 470 provided by dynamic optical actuation taken along axis AA of Figure 4A. Finally, Figure 4D shows the combined power of the dynamic electro-active optics and the fixed enhancement regions taken along axis AA of Figure 4A. As is clear from the figure, the top and bottom distortion blending regions 450 of the dynamic electroactive optics are external to the mating point 410 and the enhanced read zone 440 and channel 430. 5A and 5B illustrate an embodiment in which dynamic optics 520 are positioned below mating point 510 of low add power enhancement lens 500. In Figure 5A, the position of the dynamic electroactive optical blending zone is traced down along the wearer's eye to enhance the aisle 530 resulting in significant total distortion 550. In some embodiments of the invention, this is resolved by delaying the activation of dynamic optics until the wearer's eye passes over the upper edge of the blending zone of dynamic light 121818.doc-35-200807055. Figure 5B shows the power along axis AA of Figure 5A. The visible distortion region 550 overlaps the add power of the lens directly below the mating point and further exhibits the need to delay the activation of dynamic optics until the eye passes over the region. Once the eye passes over this area and enters, for example, the read area 54, there is no significant optical distortion. In one embodiment of the invention, an extremely narrow blending zone of 1 mm to 2 mm can be provided to allow the eye to quickly pass over this zone. In an embodiment of the invention, the horizontal width of the dynamic optics can be between about 24 mm and about 40 mm. In another embodiment of the invention, the horizontal width of the dynamic optics may be between about 30 mm and about 34 mm. In another embodiment of the invention, the horizontal width of the dynamic optics can be about 32 mm. Thus, in some embodiments of the invention, the shape of the dynamic optics is more similar to an ellipse, wherein the horizontal measurement is wider than the vertical measurement. Figures 6A-6C show an embodiment of dynamic optics. In the illustrated embodiment, the dynamic optics have an elliptical shape and a width of between about 26 mm and about 32 mm. Showcase the various heights of dynamic optics. Figure 6A shows dynamic optics with a height of approximately 14 • mm. Figure 6B shows dynamic optics at a height of about 19 mm. Figure 6C shows dynamic optics with a height of approximately 24 mm.

Visionix's current state of the art PowerMapVM 2000TM High Precision Lens Analyzer" measures and produces a map of unwanted astigmatism, which is used by lens manufacturers when manufacturing or designing PAL The same device for measuring and verifying the quality control and marketing specifications of its own PAL 121818, doc-36-200807055.

Figures 7A-7K clearly show a significant improvement in the enhanced lens made by the method of the present invention over the current state of the art. Embodiments of the invention shown in Figures 7A-7K have significantly less distortion, significantly less unwanted astigmatism, wider channel width, and lower add focus when compared to current state of the art PAL lenses. Degrees and higher added focal lengths are slightly shorter. The method of the present invention can provide such significant improvements while allowing the user to see at a distance, at a medium distance, and at a close distance, using conventional PAL lenses. The invention further encompasses that depending on the wearer's pupil distance, the fit point, and the size of the cut frame edge, dynamic optics may need to be eccentric with respect to the enhanced region and, in some cases, horizontal. However, in all cases, when the dynamic optics is eccentric with respect to the enhancement region, it remains optically transferred to the region when the dynamic optics are activated. It should be noted that the vertical dimension of the edge or edge of the frame determines this amount of eccentricity in many cases (but not in all cases). 121818.doc -38- 200807055 The ophthalmic lens of the present invention allows optical transmission of 88% or higher. If an anti-reflective coating is applied to both surfaces of the ophthalmic lens, the optical transmission will exceed 90%. The optical efficiency of the ophthalmic lens of the present invention is 9% or better. The ophthalmic lens of the present invention can be coated by a variety of well known lens treatments, such as, for example, antireflective coatings, scratch resistant coatings, cushioning coatings, hydrophobic coatings, and ultraviolet coatings. The UV coating can be applied to an ophthalmic lens or dynamic optics.
