Description

LENS WITH CORRECTION OF "SURFACE" DESCRIPTION OF THE INVENTION The present invention relates to improvements for eyeglasses in the use of spectacles of the folded type or armor, such as sun glasses, eye protection goggles, whether transparent or color, and safety glasses While much of the following description, and indeed the description of the examples, will refer to flat lenses, it should be understood that the lenses of the invention may also be of the prescription type. Folded type or armor traditionally provide a very broad field of vision, and therefore are often the preferred choice of eyeglasses, either in sun glasses, safety glasses or other forms of protective eyewear, for sports, protection eyeglasses and the like It is known from the prior art how to fabricate bent glasses around planes (non-corrective) having segments bent at and designed to protect the eye from incident light, wind, and foreign objects in the field of temporary peripheral vision user. Structures bent around for eyeglasses of this type, in the absence of lenses, allow light to enter the eye from wide angles to approximately 120 ° from the primary line of sight. However, the lenses of the technique Previous for glasses of this type compromise the field of vision achieved by the structures. It has not been possible in traditional folded eyeglasses to avoid this diminished vision in the peripheral region. Therefore, traditional folded around spectacles often give rise to reduced recognition of the objects in the temporary peripheral vision user's field (as a result of a vision in the size of that field of view). Additionally, such traditionally folded spectacles, often at least cause the displacement of the objects in a field of the temporary peripheral vision user, thereby interfering with the peripheral perception of the user of such objects. In addition, such traditional folded around spectacles normally exhibit a degree of off-axis stain experienced with gaze fixation angles from the primary line of sight. It is an object of the present invention to provide lenses for use in spectacles of the folded type around, whose lenses will improve the user's peripheral field of vision and peripheral perception of the objects, the improvement that seeks to restore the peripheral field of vision of the user and the perception of objects that are closer to those that when glasses are not used. The invention also aims to provide lenses that can advantageously and additionally reduce the off-axis stain in the optical zone thereof. Accordingly, it is an object of the present invention to overcome or at least reduce, one or more of the difficulties and deficiencies related to the prior art. The present invention provides an optical lens element adapted for mounting on a frame of the folded-around type, the lens element including a front and rear surface, capable of providing an optical zone and a peripheral time zone including a surface correction for improve the general field of vision of the user. The optical lens element according to the present invention therefore provides the user, in the peripheral time zone, with increased recognition of the objects and a substantially improved perception of the correct object location. The field of view can therefore be increased, for example, up to approximately 2.3 °, where the surface correction completely compensates for the prismatic errors in the peripheral time zone. Preferably, the lens element * in the optical zone further includes a first correction for improving vision by reducing the spot off the axis and / or a second Correction in the optical zone to help ensure that the primary line of sight has no disturbance. Both additional preferred corrections are described below. The optical zone of the lens element is the area where it is intended to provide direct, generally clear vision as the eye's observation line rotates around its primary direction ("straight forward") as it would during typical eye movements. In this regard, it is desirable that the optical zone include at least those lens portions that are used during eye rotations of up to 50 ° on the temporary side, up to 45 ° on the nasal side, and up to 30 ° vertically upwards and down from the primary observation line (straight forward) with the lenses in the position as they are used. The optical zone will preferably be planar (or zero refractive power), and the description of the preferred embodiments of the present invention generally describes only a planar configuration. However, it will be appreciated that the optical zone may be a prescription power of less or more power. In this regard, the optical zone of the optical lens element of the present invention can generally be described as including a prescription zone or Rx. The modality where the optical zone is flat can be considered as a specific case of it (Zero power Rx). The ophthalmic lens element can therefore be a flat lens (or zero refractive power), or a negative or positive refractive power lens. Before describing the various preferred features of the lens element of the present invention, it should be appreciated that the term "optical lens element" refers to a finished optical or ophthalmic lens, or a lens lens formed from a pair of discs. of lenses that can be used in the formation of an optical lens product. In this regard, when the optical lens element includes an ophthalmic lens disc, the peripheral time zone may be provided by the front disc or the posterior disc. The ophthalmic lens may include a spherical, aspherical, toric, atoric surface or any combination thereof and may exhibit an astigmatic correction. In addition, the optical lens element can be an individual, bifocal or progressive vision lens. Applicants have discovered that it is possible to provide an extended field of view in a lens of the folded-over type, while allowing the lens to form an optical zone, and even to still provide a lens that provides a shell in the area of the temples. . This is achieved by having a surface correction in the peripheral temporal zone In relation to this surface correction, beyond the optical zone (on the peripheral temporal side of the lens element), the horizontal component of the prism (as determined normal to one of the lens surfaces), preferably varies uniformly from the base nasal values, which are characteristic of the optical zone to the base temporal values, which are characteristic of those regions of the lens element of the present invention that are used for extreme temporal peripheral vision. This is in contrast to the existing flat lens elements where the prismatic power continues to increase in the nasal base direction towards the periphery of the lens element. The preferred nature of the surface corrections can be easily understood by defining a meridian on a lens element and referring to the prism in relation thereto. Therefore, consider a meridian of a lens element, the meridian that is horizontal when the lens element is in the position as it is used, and the meridian that passes through the lens center. Then, consider the horizontal component of the prism (as measured normal to one of the lens surfaces) at points along this meridian that lies between the lens center and the frame boundary.

Preferably, the value of this horizontal prism component at the point of intersection of the user's line of sight and the lens surface will be close to zero or in a nasal base direction. However, this prism component preferably varies continuously along the meridian, and obtains a maximum value in a nasal base direction at some point along the meridian. In the preferred form of the maximum nasal base prism point it will be at, or near, the boundary of the optical zone. Then, as mentioned above on the peripheral temporal side of the lens element, beyond the maximum base nasal prism point, the horizontal component of the prism (as measured normal to one of the lens surfaces), is preferably reduced uniformly in value up to at least 0.1 prism diopter, more preferably at least 0.25 prism diopter less than the maximum value. In a further preferred embodiment, the horizontal component of the prism is uniformly reduced from the maximum base nasal prism value by an amount in the range of 0.1 to 2.5 diopters of prism, at the temporal end of the lens element. Preferably, the reduction in the nasal prism -base is in the range of 0.75 to 2.0 diopter prism, greater preference in the range of 1.3 to 1.9 diopter prism. The horizontal component of the prism can be reduced to a value of substantially zero or can reach base time values. Therefore, in the position as used, the level of the prism at the extreme limit of vision, for example at the edge of the frame, is substantially reduced to zero. The prismatic lens effect in the temporal peripheral region is determined by the eye with the lens in position as it is used in terms of light beams entering the entrance pupil that is close to the position of the iris immediately in front of the crystalline lens inside the eyeball. This is the effective aperture stop through which light from the extreme temporary peripheral regions passes before being detected by the retina. Referring to the input pupil the level of the horizontal component of the prism achieves maximum values in a nasal-base direction at, or near the limit of the optical zone. In the region of the temporal side of the optical zone, the horizontal component of the prism may uniformly reduce to substantially zero lower base nasal values, or base time values.

Alternatively, beyond the maximum base nasal prism point, the horizontal component of the prism remains substantially constant, that is, it represents a prism value up to ± 0.1 diopters of prism. It has surprisingly been found that while a prism correction in the temporal peripheral zone can substantially completely compensate for prismatic errors, the user, in use may be aware of a disturbance in his object field. Accordingly, it is preferred that the placement and / or degree of application of the peripheral prismatic correction be such that any perception of the users of the peripheral image distortion or the movement / vestibular effects is reduced or eliminated. The experience of the users has revealed that a small percentage of cases reported negative reactions to the base prism application if the changes go beyond the limits very close to the optical zone (through the region traversed by the line of vision during eye rotation). end) and / or the degree of surface modification is too large or too fast. In order to reduce or eliminate any possibility that sensitive users might experience disturbed visual fields, it is preferable to move the surface modification temporarily and / or reduce the degree of, or the rate of change of, the horizontal peripheral prism. For example, the starting point of the surface modification can be 22.5 mm (or 57 degrees of ocular displacement). Alternatively, or in addition, the degree of prismatic correction that can be reduced to less than 100%, preferably approximately 80% to 95% of that required to completely eliminate the prismatic error at the extreme limit of the field of vision. In a further preferred form of the present invention, the front and / or back surface of the optical lens element may further include a surface correction to compensate at least partially for prismatic errors in the primary observation line (the viewing zone). straight forward "). Preferably, the surface correction can be a prismatic correction. For example, the prismatic correction may be a base or nasal base correction applied to the front and / or posterior surface. In fact, in a preferred form of the invention, the front and rear surfaces of the lens element are preferably both inclined with respect to each other at the center of the lens. This inclination is preferably such that when the lens is in a condition As used, the primary line of vision does not support the angular deviation in a horizontal plane when it passes through the lens. Typically, this will require the back surface to be inclined relative to the front surface by approximately 0.4 ° towards the nasal side of the lens, resulting in a base nasal prism of approximately 0.4 diopter when determined normal for the surfaces. This inclination value will of course depend on several factors such as the lens shape, the tilt of the frame and the lens material. For example, the temporary prismatic errors of base for straight vision that are a consequence of the oblique observation through highly inclined lenses lenses, the surfaces can be corrected with the base nasal prism - normally 0.4 prism diopter for a lens element of base 8, formed from polycarbonate and exhibiting a center thickness of 1.8 mm and 20 ° rap. Recalling this, it will be appreciated that one form of the present invention therefore includes a configuration in which the two prismatic corrections are provided, one in relation to the primary observation line and one in relation to the temporal peripheral vision. In addition, the front and / or rear surfaces of the lens element in the optical zone may be atoric, aspheric, toric or spherical or any other shape complex An aspheric or atoric surface can be selected to minimize off-axis optical astigmatism, any errors in off-axis optical power from the plane, or in fact to minimize any off-axis stains that are derived from such astigmatism or power errors. Typically, this will result in a back surface curve that becomes flatter, or a front surface curve that becomes alternating from the center of the lens. In summary, and in relation to the peripheral regions of the lens element of the present invention, it will be appreciated that the light that enters obliquely through the highly curved surfaces introduces a nasal prism base, which in turn has the consequence of reducing the user's field of vision. In this regard, in some lenses bent around the prior art, there would be a field loss in each eye of approximately 2.3 ° from some 4 diopters of the prism with a typical flat extension. However, in contrast to the optical lens element of the present invention, it reduces the aforementioned field loss without compromising optical lens performance in the optical zone. In addition, other preferred embodiments of the present invention additionally introduce corrections to improve vision in the optical zone by reducing the off-axis stain, and to ensure that the primary line of vision has no disturbance, thus reducing visual fatigue. Alternatively, in another form of the invention, the front surface of the lens element is preferably capable of being mounted on a curved frame of constant design of between 6.00 D and 12.00 D or more, but preferably between 8.00 D and 9.00 D. , the front surface of the lens element may have a high curve extending from the nasal to the temporal limits, although the vertical curve is preferably 6.00 D or less. Therefore, it will be understood that such vertical curves allow the final lenses, preferably the bisected lenses, to be adapted to the shape of the user's face and thus locate closely in a shape of the folded type around (the so-called "toric" design). ). In addition, in order to create an effectively larger diameter lens pattern suitable for bent frames extending toward the temporal edge, the design center may be offset from the lens model at some nasal distance from the geometric center of the lens. lens, for example about 10 mm. This places the center of the design near the user's normal direct observation line, at the same time retaining the appropriate lens material on the temporary edge to adjust the frame.

The optical lens elements of the present invention may be provided in various forms, such as in the form of a unitary lens adapted for mounting on a frame of the folded-around type. In a particularly preferred embodiment, the present invention can provide a spectacle structure, or a unitary lens, having a pair of optical lens elements, whose lens elements provide the actual correction in an optical zone for a user up to 50 °. outside the axis, and ending in a peripheral temporal zone. This particular preferred embodiment improves the perception of user objects in their peripheral vision area, the improvement that aims to restore that vision to normal (ie, when no glasses are used at all). • In a further aspect of the present invention, it can provide an optical lens element adapted for mounting on a shell of the folded-around or shell type, such that the lens element is temporarily rotated about a vertical axis through the center of design thereof, the lens element including a front and rear surface capable of providing an optical zone and a peripheral time zone including a surface correction to improve the general field of view of the user, the front surface and / or posterior that supports a surface correction at least partially adjusting for errors that include astigmatism and power errors. In a preferred aspect of the present invention, as stated above, the optical lens element may be formed as a sheet of a front and rear lens disc. Accordingly, in a preferred aspect of the present invention there is provided a laminated optical article, adapted for mounting on a shell of the folded-around or shell type, which includes: a front lens disc, and a complementary rear lens disc; the front and rear lens discs of the laminated optical article defining an optical lens element including a front and rear surface capable of providing an optical zone and a peripheral zone; the front and / or back surface in the peripheral temporal zone supporting a prismatic correction so that the horizontal prism component varies uniformly from the base nasal values to substantially zero through the zone; the frontal and / or posterior surface in the optical zone that support a prismatic base nasal correction until at least partially compensate for the errors binoculars in the primary line of vision of the user in the position as used. Preferably the front and / or rear surface further includes a surface correction to at least partially adjust the optical errors that include astigmatism and medium power errors. The ophthalmic lens can be formulated from any suitable material. For example, a polymeric or glass material can be used. The polymeric material can be of any suitable type. The polymeric material may include a thermoplastic or thermosetting material. A material of the diallyl glycol carbonate type, for example, CR-39 (PPG Industries) can be used. Alternatively, a polycarbonate material can be used. In a further aspect of the present invention, there is provided a method of designing an optical lens element adapted for mounting on a shell of the folded-around or shell type, the method of which includes providing a mathematical or numerical representation of a first surface of an optical lens element that includes a section designed to provide the desired prescription (Rx) in the optical zone, and add to it a mathematical or numerical representation of a peripheral temporal zone; and a mathematical or numerical representation of a transition section designed to uniformly combine the prescription zone and the peripheral temporal zone to define a complete lens surface; and modifying the representation of the lens surface to introduce a prismatic correction in the peripheral temporal zone to improve the general field of vision of the user. In a preferred aspect, the method may further include modifying the representation of the lens surface in the optical zone to provide a prismatic correction in the optical zone so that the primary line of vision does not substantially experience angular deviation in a horizontal plane as it passes. through the lens element. In a further preferred aspect, the method may further include providing a mathematical or numerical representation of a second surface of an optical lens element that includes a section designed to provide the desired prescription (Rx) in the optical zone and optionally add to it a mathematical representation or number of a peripheral time zone to define a second full lens surface; optionally rotating and / or decentering the representation of the lens surfaces to allow mounting in a suitable frame, and modify the representation of the lens surfaces to adjust at least partially the optical errors induced in the peripheral zone and the optical zone that they include astigmatism and medium power errors. In relation to these methods, it will be appreciated that the reference to "desired prescription (Rx) in the optical zone" includes a zero power prescription for the preferred planar mode. In this regard, when a lens element according to the present invention has a power other than zero, it will be appreciated by someone with experience that minor consequential alterations may need to be made for the configurations described herein. The present invention will be described more fully with reference to the figures and examples that accompany it. It should be understood, however, that the following description is illustrative only and should not be taken in any way as a restriction of the generality of the invention described above.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic representation of the lens of the lens coordinates mentioned in the example; Figure 2 is a schematic representation of the lens parameters mentioned in the example; Figure 3 is a schematic illustration of a flat lens element, illustrating a loss of visual field at the angle f in the peripheral zone, the entrance pupil E of the eye, the posterior vertex B of the lens, and the angle? (on the side of the eye) of a peripheral beam relative to the straight direct observation direction; Figure 4 illustrates how the viewing angle B is measured relative to the pupil of entry of the eye; Figure 5 illustrates the prismatic displacement of the objects where the field loss is approximately 2.3 °; Figure 6a is a horizontal section through an optical lens element according to the present invention; Figure 6b is a vertical section through an optical lens element according to the present invention; Figure 7 is a graph of horizontal section thickness (normal to the front surface) against the distance of the lens design center; Figure 8 is a graph showing the horizontal prism along the temporal nasal axis as measured normal to the front surface; In greater detail, Figure 8 illustrates how the horizontal prism varies through a series of lens elements according to the present invention. The dotted line DP represents the horizontal prism for an off-center plane lens, typical of the prior art for which a simple correction for prismatic deflection has been made from the straight view. In both cases, the horizontal component of the prism is observed to continue increasing (at about a fixed speed) in the base nasal direction outside the optical zone according to the distance from the center of the lens increasing on the temporal side. OZ represents the optical zone of the lens elements according to the present invention. TZ represents the peripheral time zone of the lens elements according to the present invention. CB represents the center of the lens model. It will be observed that the modalities are represented by graphs 1, 2 and 3 are deviated from a typical decentralized plane DP in particular in the peripheral temporal zone (T) where the prism reduces uniformly and quickly from the base nasal values to zero or the base temporary values. As best seen in Figure 9, Figure 1 illustrates the case where the prismatic peripheral deviation mentioned at the entrance pupil is substantially reduced to zero (or less). However, applicants have discovered that this substantially complete prismatic correction can lead to a disturbance in the user's object vision at the extreme periphery of vision. Thus, a less than complete prismatic correction, as illustrated in Figures 2 and 3, may be preferred in some circumstances. Similarly, as best seen in Figure 7, the prism correction in the peripheral temporal zone is represented by a slight increase in lens thickness relative to a typical decentralized DP plane towards the periphery thereof. This is advantageous for adjustment purposes as the lens has a more uniform edge thickness and is more consistent and therefore less prone to kinking or breaking during the beveling process. EXAMPLE The following example describes a generally flat lens with a modified prism periphery that reduces the peripheral vision loss of the user. He example refers to a lens that is made of a material of a refractive index of 1586. 1. The frontal surface is convex spherical with a radius of curvature of 65.43 mm. 2. The back surface is concave. It can be conveniently described in terms of its perpendicular distance z from the tangent plane (TP) of the back surface (BS) at the lens center (LC). Leaving z = z (r,?) Where, r,?, Are polar coordinates in the plane (see Figure 1). The axis ? = 0 corresponds to the nasal side of the horizontal axis (HN) of the lens in the configuration as used, and? = p corresponds to the temporal side. 3. The optical zone is defined as the lens region described by 0 < r < R, where R (?) = Rx + (R0 - i) (1 + eos?) In this formula, Ro and Ri are radial limits of the optical zone (OZ) in the nasal (N) and temporal (T) regions respectively. A convenient selection is Ro = 27.5 mm, and Ri = -17.5 mm. 4. Within the optical zone, a convenient selection for z (r ,?) could be Z (r>?) = ÍSC -j, .. kkr- C0S2"'- *)? Sin? J =? ¿= O where the Cjíl coefficients are given in the following table: . Outside the optical zone, z can be conveniently described in the form of a polynomial in the radial coordinate r, z (r, T) = a (?) + B (?) (RR (?)) + C (?) (rR (0)) 2 + d (?) (rR (T)) 3 for r > R (T) Using well-known mathematical techniques, it can be shown that the requirement that z and the first and second partial derivatives of z with respect to ar, each being continuous across the optical zone limit r = R (?), Will only determine the values of the coefficients a (0), b (?) and c (0). The coefficient d (?) Remains unassigned and can be used to achieve the desired prismatic behavior. A convenient way to proceed is to require z to obtain a prescribed value at a specified radius r = R8 per say. In particular, the following choices can be made: Roo = 42.5 mm z (R8?) = Yes + * í TS0 - Yes) (1 + eos?) where SO = 16.00 mm and Si = 16.75 mm. Here S0 and Si represent the surface heights in _R8 on the nasal and temporal sides respectively. From this requirement, the coefficient d (?) Can then be determined using standard mathematical techniques. However, it will be understood that the observation lines of the two eyes of the user would need to be directed inward (each by the angle?) To form an individual image of a direct distant object. This would usually be considered an undesirable condition, since it leads many people to headaches, eyestrain and other forms of visual discomfort. The front and back surfaces are placed one in relation to the other so that the design center, the normals to the two surfaces make an angle of 0.32 degrees for each one in the horizontal plane in such a way that they create the base nasal prism . The lens thickness in this lens center, measured normal to the front surface should be, for example, 1.8 mm. The lens must be mounted on a folded and used frame in such a way that the primary line of sight ("straight forward") intersects the posterior surface at the design center, and makes an angle with the normal toward the posterior surface at that point of 20 degrees in the plane horizontal. The lens is then subjected to a right prism correction in a known manner. For a typical 8 D lens, a prismatic correction of approximately 0.36? Nasal base may be required. 1. Peripheral Prismatic Deviation This example describes the prismatic errors and the loss of field of view associated with a typical off-centered flat lens of the prior art. It also shows how to improve the field of vision and the reduction in the blind spot in a typical temporary folded frame limit of 115 ° measured from the entrance pupil. The entrance pupil, typically estimated at 13 mm behind the lateral surface of the lens eye, is the appropriate point of entry into the eye of the bundles that enter from the peripheral area when the direction of observation is directly straight. With reference to Figure 2, there exists a spherical decentralized prior art lens having the following characteristics: R = C2B = 66.25 mm The lens surfaces with centers Ci for the front surface and C2 for the rear surface. CXC2 = 1.1 mm to = lens thickness = 1.8 mm M = material refractive index = 1.586 E = eye input pupil EL = line of sight A = beam entry point in ipico frame boundary? = angular output beam that it makes with the input beam Consider more from a distant object that intersects the front surface at A at a normal angle of incidence of 51 ° with reference to the normal surface CiA. After the refraction in A The beam is refracted to position B on the surface of the eye side. The surface normal at B is different from that at A by the angle f. f tQ t? in? i + C C f = arctan _ 2 1. 8 tan 29.344- 1.1 '= arctan 66.25 = 1.82 ° The angle of incidence in B? 2 = (?

The prismatic effect is:? = 100 so? ? = 4.0 nasal base? This creates an effective blind region (d) of size 40 cm at a distance of 10 m (Figure 5). LENS OF THE PRESENT INVENTION Referring again to Figure 2, the surface of the eye side of the lens is adjusted to create the prism outside the base (measured normal to the lens surface). Again, for example, at the typical temporal edge of the frame, the surface of the eye side is rotated at B in the direction of the prism off base at 0.95 °.

The incident angle in B now becomes? 2 = 31.16 - 95 = 30.21 °? 3 = arcsen 1.586 sin 30.21 ° = 52.94 °? = (? 3 - F) - 51 = 0.12 ° nasal base. This angle of deviation is equivalent to 100 so 0.12 = 0.21? of the base nasal prism. With the lens used in this configuration illustrated in Figures 3 and 4, the peripheral prismatic values, the angle of deviation of the input beam and the displacement of objects at 10 m distance are shown. The improvement of the field of vision and the reduction of the displacement of objects in the blind spot are also shown. The values are for the previous example at incident beam angles of 115 ° to the entrance pupil.

Referring to Figure 5, a prism dioptric deviation of prism 3, which corresponds to a field loss of 2.3 °, is characteristic of existing plane lenses at 115 ° of temporal ocular angle. For an object distance of 10 meters, the value of d (object displacement) is 40 cm. This displacement is effectively brought to zero after correction of the peripheral prism according to the present invention. 2. Calculation of Optical Lens Element Surface For a lens that has a frontal sphere that has 8.00 D, and a posterior sphere, the following is maintained: For a lens that has a back sphere that has 09 D and a front sphere, the following holds: 3. Finally, the Cartesian coordinates for the horizontal and vertical sections for an optical lens element according to the present are set forth below. The horizontal and vertical sections thus defined are illustrated in Figures 6a and 6b respectively. Horizontal section Vertical section Finally, it is understood that various other modifications and / or alterations may be made without departing from the spirit of the present invention as defined herein.
