Description

Lens to which vision correction pattern is applied and manufacturing method}

The present invention relates to a lens to which a vision correction pattern is applied and a manufacturing method, and more particularly, in a lens to which the vision correction pattern is applied, the lens is provided on a raw material lens substrate and on the substrate, The first layer is made of a low-refractive material layer, and a high-refractive material layer and a low-refractive material layer are repeatedly deposited from layers 2 to 8 to 12 to prevent near-infrared rays and reflection, and are provided on top of the multi-layer, It includes a super water-repellent layer deposited to a thickness of 30 to 40 nm to protect the multi-layer, and pinholes are provided at regular intervals in at least one or a plurality of layers of a low-refractive material layer and a high-refractive material layer constituting the multi-layer It is a technical field related to a lens to which a vision correction pattern is applied and a manufacturing method, characterized in that the vision correction pattern is formed.

In general, light is a type of electromagnetic wave that can enter the human eye and create a visual signal, and includes visible light (wavelength 380nm to 780nm), ultraviolet (short wavelength 380nm or less) and infrared (long wavelength 700nm or more). It also includes gamma rays.

In general lenses, ultraviolet rays pass through and contact the user's cornea, causing eye damage such as cataracts, erythema, keratitis, or near-infrared rays passing through to the user's skin epidermis, upper dermis, deep dermis and muscles, and thermal action occurs. , It weakens fibroblasts in the deep dermis, destroys collagen, and decomposes elastin to dry the skin while skin aging, wrinkles, light sensitivity, telangiectasia, and other skin diseases and cataracts, keratitis, conjunctivitis, etc. In order to solve this problem, lenses that block visible light (blue light), near-infrared light, and glare have been developed.

The visible light has a range from 380nm to 780nm, and refers to a wavelength range in which a person sees objects as light from the purple series (wavelength about 400nm) to the red series (wavelength about 700nm).

In particular, blue light among visible light is blue light, which means the blue wavelength band among visible light, and is light of a wavelength that is irradiated from electronic devices such as computers, smartphones, and TVs to brighten the screen. It is a harmful ray of light that makes you feel glare, causes eye fatigue, interferes with biorhythms, and even causes sleep problems.

The blue light is a short wavelength between 380nm and 500nm in the visible light range.Because the wavelength is short, the image is formed in front of the retina and is not clearly recognized.Therefore, the color is dispersed, causing eye fatigue, and strongly stimulates the eye cells. As a result, there was a problem of increasing the glare and further increasing the tiredness of the eyes. Recently, a large amount of blue light is included in displays such as TVs, computer monitors, smartphones, and tablet PCs, which intensifies stimulation of the optic nerve, causing a problem of sharply deteriorating visual acuity.

As an example of a conventional blue light blocking spectacle lens for solving the above problems, Korean Patent Registration No. 10-1790465 includes a spectacle lens and a coating layer formed on the front surface of the spectacle lens, and the coating layer emits blue light on a transparent synthetic resin material. It is formed by attaching a film containing an agent and a sunscreen agent to the front surface of the spectacle lens, and blue light input through the blue light emitting agent is emitted to the side of the coating layer formed by the film. In addition, since blue light that is not emitted by the yellow dye is absorbed, a blue light blocking spectacle lens having an effect of blocking double blue light is proposed.

However, the prior art Korean Patent Registration No. 10-1790465 is a spectacle lens that blocks only one visible light (blue light), and has a problem in that it cannot prevent all visible light (blue light), near-infrared light, and glare.

On the other hand, as an example of the prior art for solving the above problem, Korean Patent Registration No. 10-1612940 discloses a polymerization initiator that converts the monomer into a polymer by reacting with a monomer, which is a raw material of a plastic lens whose refractive index varies according to physical properties. As a mixture of a UV absorber that absorbs ultraviolet rays from a plastic lens that has been mixed and converted into a polymer, and a transparent material that minimizes the phenomenon that the plastic lens that has been mixed with a monomer and converted into a polymer looks yellow to make it appear transparent, As the blocking rate for short-wavelength ultraviolet rays and long-wavelength ultraviolet rays of 380~400nm is remarkably high, even blue light of 380~500nm can be absorbed and blocked with a high blocking rate, thus enhancing health promotion effect.The transparent material makes the lens yellow. It proposes a functional spectacle lens that blocks ultraviolet and blue light that minimizes the appearance and allows you to see natural light without distortion.

However, the prior art Korean Patent Registration No. 10-1612940 is a spectacle lens that prevents ultraviolet (blue light) and dazzling, and has a problem in that it cannot prevent all visible light (blue light), near-infrared light, and glare.

However, specific examples introduced below are provided as examples in order to sufficiently convey the spirit of the present invention to those skilled in the art.

Therefore, the present invention is not limited to the specific examples presented below and may be embodied in other forms, and the specific examples presented below are only described to clarify the spirit of the present invention, and the present invention is not limited thereto.

At this time, unless there are other definitions in the technical terms and scientific terms used, they have the meanings commonly understood by those of ordinary skill in the technical field to which this invention belongs, and unnecessarily obscure the subject matter of the present invention in the following description. Description of possible known functions and configurations will be omitted.

In addition, the singular form used in the specification and the appended claims may be intended to include the plural form unless otherwise indicated in the context.

In the present invention, a line perpendicular to the boundary surface of the lens 100 is called a normal line. In this case, the angle between the incident light incident on the lens 100 and the normal line is called the incident angle, and when the incident light passes through the lens 100 The lens 100 is bent at an angle due to the difference in the medium of the lens 100, and at this time, the angle between the bent light and the normal is referred to as a refraction angle.

In the present invention, the term'low refractive material' refers to a material having a refractive index of 1.5 or less, and the refractive index refers to the rate at which the speed of light in the spectacle lens 100 decreases when light enters the spectacle lens 100. , sin is equal to the refraction angle divided by the sin incident angle. Therefore, the smaller the refractive angle with respect to the standing angle, the smaller the refractive index.

In the present invention, the term “high refractive material” refers to a material having a refractive index exceeding 1.9, and refers to a material having a refractive angle with respect to an incidence angle is relatively larger than that of the low refractive material.

In addition, in the drawings of the present invention, the thickness is enlarged in order to clearly express various layers and regions.

In addition, when it is said that the other part is "lower", this also includes the case where the other part is "right below" as well as the case where there is another part in the middle.

The substrate 10, which is the main component for achieving the present invention, is

As shown in FIG. 1, as a receiving object through which light passes, refracts, diffracts, and reflects, it is possible to correct a user's field of view or vision by laminating various deposition materials on the substrate 10.

Specifically, the substrate 10 is an episulfide resin, polycarbonate resin, acrylic resin, poly4-methylpentene resin, diethylene glycol bisallyl carbonate resin, allyl carbonate resin, polyether resin, polyester resin, isocyanate compound and poly Polyurethane resin reacted with a thiol compound, a transparent resin obtained by curing a polymerizable composition containing a thioepoxy compound having at least one disulfide bond in a molecule, and a transparent (translucent) material such as inorganic glass, convex lens, concave Lenses, flat lenses, lenses for nearsightedness, lenses for farsightedness, lenses for astigmatism, magnifying lenses, lenses for screens, etc., can be used in various ways depending on the cases required for use.

In addition, the substrate 10 may be any such as glass or plastic, but such as polyurethane resin, episulfide resin, polycarbonate resin, acrylic resin, polyethersulfone resin, diethyl glycolbisallyl carbonate resin, etc. It is more preferable to be made of plastic.

In addition, the substrate 10 of the present invention uses a material having excellent transparency on the surface and excellent adhesion to the substrate 10, and uniformly coating a hard coating agent on the surface of the substrate 10 to make the substrate 10 A hard coating layer is provided to prevent scratches on the surface.At this time, methods such as spin coating, flow coating, dip coating and spray coating can be used as the hard coating method, and to ensure the uniformity of the thickness of the coating film. For this, it is preferable to use a method using spin coating or dip coating.

Specifically, the hard coating agent may be hard coated using a material such as a compound having a plurality of epoxy groups, a vinyl acetate-based resin, and a photo cationic polymerization initiator.

As the compound having a plurality of epoxy groups, a bisphenol A type epoxy compound, a bisphenol F type epoxy compound, a phenol novolak type epoxy compound, a cresol epoxy compound, an aliphatic glycidyl ether type epoxy compound, and the like may be used.

The vinyl acetate-based resin includes polyvinyl butyral, polyvinyl ether, polyvinyl oxide, polyvinyl acetate, and the like, and natural polymers such as ethylhydroxyethyl, carboxymethylethyl, hydroxyethyl, and the like may be used.

The photo cationic polymerization initiator is an onium salt such as an iodonium salt (aromatic iodonium salt), a sulfonium salt (aromatic sulfonium salt), a halogen-containing compound such as an S-triazine derivative, a sulfone compound, a sulfonic acid compound, a sulfonimide A compound, a diazomethane compound, etc. can be used.

On the other hand, the substrate 10 is composed of a central thickness of 1.3 to 1.7mm, if it is configured to be less than 1.3mm, it may be configured too thin to cause a risk of damage, and if it exceeds 1.7mm, the internal transmittance is It is preferable to be configured to have a thickness within the above range because it increases proportionally and the appearance and weight as a spectacle lens may be relatively deteriorated. More preferably, it is preferably composed of 1.4 to 1.6mm.

The main component for achieving the present invention, the multi-layer 20 is

As shown in Figure 1, provided on both upper surfaces of the substrate 10, the upper one layer of the substrate 10 is made of a low-refractive material layer 21, from the 2nd to the 8th to 12th layers The high refractive material layer 22 and the low refractive material layer 21 are repeatedly deposited to prevent near infrared rays and reflection.

In addition, one layer of the substrate 10 should be made of a low refractive material layer 21, and the substrate 10 made of a plastic material and a deposition material made of a metal oxide, that is, a multi-layer 20 Defilming may occur due to different coefficients of expansion and contraction due to thermal change. When the high refractive material layer 22 is used for the first layer, the substrate 10 and the multi-layer 20 may be separated by an external impact. It can be separated, and by using the low refractive material layer 21 in the first layer, the adhesion to the substrate 10 is increased to prevent the film from being detached due to external stress (shock).

As a component constituting the low refractive material layer 21, for example, silicon dioxide and aluminum oxide may be used alone or in combination.

In the present invention, it is preferable to use it by mixing rather than using it alone, but when mixing, the composition ratio is silicon dioxide (Silica, SiO ₂ ) and aluminum oxide (Aluminium Oxide, Al ₂ O ₃ ) 5 to 8: mixed with 2 to 5 As a result, it is possible to enhance hardness and adhesion (defilming), which are disadvantages of silicon dioxide.

The silicon dioxide is a transparent, low-refractive material having a relatively low refractive index that transmits in a wide wavelength range of 200 to 4500 nm, and has excellent durability and is strong against external environmental changes, so it is widely used for an anesthetic coating and a protective layer of a metal thin film. The silicon dioxide thin film has a characteristic that physical properties such as density, absorption rate, and refractive index change according to vacuum deposition conditions such as vacuum degree, deposition temperature, deposition method, substrate temperature, oxygen pressure, and deposition rate.

However, when only the silicon dioxide is used, the disadvantage of low hardness and adhesion is maximized, so that the substrate 10 and the film may be removed frequently.

The aluminum oxide is a transparent low-refractive material having a relatively low refractive index that transmits at more than 300 nm, and the aluminum oxide thin film has good adsorption power to metals such as glass, most oxides, and aluminum, and the degree of vacuum, deposition temperature, and deposition method. , Physical properties such as density, absorption rate, and refractive index change according to vacuum deposition conditions such as substrate temperature, oxygen pressure, and deposition rate. , It blocks harmful rays such as visible light, and there is little reflection of light, so it can reduce user's eye fatigue.

However, when only the aluminum oxide is used, there is a disadvantage of poor durability, and thus damage may occur frequently.

Therefore, in the present invention, silicon dioxide and aluminum oxide are mixed and used. When the silicon dioxide exceeds 8 weight ratio, film removal may occur due to low hardness and adhesion, which are disadvantages of silicon dioxide, and the weight ratio of aluminum oxide is reduced. If it is less than 2, since glare may occur because reflection of light cannot be reduced, it is preferable that the mixture is mixed at a weight ratio within the above range. More preferably, silicon dioxide and aluminum oxide are mixed in a weight ratio of 6:4.

On the other hand, the high refractive material layer 22 is for blocking infrared and ultraviolet (blue light) wavelengths other than visible light, and as a component constituting the high refractive material layer 22, for example, zirconium dioxide and titanium dioxide are used alone. Or it may be used in combination.

In the present invention, it is preferred to use a mixture than used alone, the mixed when the composition ratio is zirconium dioxide (Zirconium oxide, ZrO _2), titanium dioxide (Titanium dioxide, TiO ₂₎ is 5 to 8 weight ratio of from 2 to 5 It is mixed with zirconium dioxide, and can enhance the infrared blocking power, which is the advantage of zirconium dioxide, and the UV blocking power, which is the advantage of titanium dioxide.

The zirconium dioxide has a high refractive index showing transmission in a wide wavelength range of 340 to 1200 nm, and is a highly durable transparent high refractive material. It is suitable for vacuum deposition conditions such as vacuum degree, deposition temperature, deposition method, substrate temperature, oxygen pressure, and deposition rate. Accordingly, physical properties such as density, absorption rate, and refractive index are changed, and vision can be protected by blocking the near-infrared region.

However, when only the zirconium dioxide is used, infrared blocking power can be increased, but ultraviolet rays cannot be blocked.

The titanium dioxide is a transparent, high-refractive material that exhibits transmission at 300 to 400 nm, has good light transmittance, excellent UV blocking power, and strong durability.Vacuum deposition such as vacuum degree, deposition temperature, deposition method, substrate temperature, oxygen pressure, deposition rate, etc. Physical properties such as density, absorption rate, and refractive index change depending on conditions, and vision can be protected by blocking the near-infrared region.

However, when only the titanium dioxide is used, UV blocking power can be increased, but infrared rays cannot be blocked.

Therefore, in the present invention, zirconium dioxide and titanium dioxide are mixed and used.When the weight ratio of zirconium dioxide exceeds 8, only infrared blocking power may be high and UV blocking power may be lowered, and when the weight ratio is less than 5, infrared blocking power may be lowered. In addition, when the weight ratio of titanium dioxide is less than 2, the UV blocking power is weakened, and when the weight ratio exceeds 5, the infrared blocking power may be weakened, and it is preferable to be mixed at a weight ratio within the above range. More preferably, zirconium dioxide and titanium dioxide are mixed in a weight ratio of 6:4.

In addition, the low refractive material layer 21 is deposited to a thickness of 0.01 to 250 nm, the high refractive material layer 22 is deposited to a thickness of 0.001 to 200 nm, the low refractive material layer 21 and the high refractive material layer 22 ) Are stacked alternately to block near-infrared rays, block blue light, and prevent glare, reducing eye fatigue and making objects appear clear, helping to correct vision.

In addition, it is preferable that the low-refractive material layer 21 and the high-refractive material layer 22 are alternately stacked. After the low-refractive material layer 21 is stacked, the high-refractive material layer 22 is stacked or If it is not alternately deposited and is laminated irregularly, the field of view may be blurred due to the reflectance or the near-infrared blocking effect may be inferior.If a problem occurs depending on the deposition conditions, it is impossible to find out which part is the problem, near-infrared, blue light, glare It is preferable to alternately and repeatedly stack the low-refractive material layer 21 and the high-refractive material layer 22 because it is not possible to block effectively and cause eye disease.

That is, the low refractive material layer 21 is stacked on the 1st, 3rd, 5th, 7th to 9th and 11th layers to prevent near-infrared, blue light and reflection to prevent eye diseases such as cataracts, keratitis, and conjunctivitis. And, since it prevents glare and makes the user's eyes comfortable, the eyesight can be corrected by making the object clearly visible, and the high refractive material layer 22 includes the 2nd, 4th, 6th, 8th to 10th layers, It is laminated on the 12th layer to prevent near-infrared and blue light, so that the eyes of users wearing glasses can be comfortably worn for a long time.

When the low refractive material layer 21 is deposited to be less than 0.01 nm, it is too thin to prevent glare, and when deposited to a thickness exceeding 250 nm, the lens transmittance may be lowered, and the high refractive material layer 22 When deposited to less than 0.001 nm, it is difficult to properly block near infrared rays, and when deposited to a thickness exceeding 200 nm, the thickness of the final lens 100 may become too thick, so it is preferable to deposit to a thickness within the above range. , More preferably, the low refractive material layer 21 is deposited to a thickness of 4.3 to 189 nm, and the high refractive material layer 22 is preferably deposited to a thickness of 0.5 to 130 nm.

In addition, the low-refractive material layer 21 and the high-refractive material layer 22 have an average reflectance of 1.5 to 2.5% in a wavelength range of 380 to 700 nm, and a near-infrared blocking rate of 40% or more. Each of the refractive material layer 21 and the high refractive material layer 22 may have different thicknesses.

When the low-refractive material layer 21 and the high-refractive material layer 22 have an average reflectance of less than 1.5% or exceeding 2.5%, the fit may be deteriorated or quality may be deteriorated, and the near-infrared ray blocking rate may be less than 40%. In this case, since it is not possible to prevent eye diseases such as cataract, keratitis, and conjunctivitis, it is preferable that the average reflectance and the near-infrared blocking rate are configured to be within the above range.

The super water-repellent layer 40, which is the main component of the present invention, is

As shown in FIG. 1, provided on the upper portion of the multi-layer 20, it is deposited to a thickness of 30 to 40 nm to protect the pinhole 30.

In addition, the super water-repellent layer 40 is configured such that the low refractive material layer 21 and the fluorine resin layer 41 are sequentially stacked to coat the surface of the spectacle lens 100, so that the lens 100 It prevents contamination from water, grease, hand marks, dust in the air, pollen, etc. on the surface, and allows it to be easily removed if contaminated.

Specifically, the super water-repellent layer 40 is any selected from polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinyl fluoride, and polyvinyldenporide, which are the low-refractive material layer 21 and the fluororesin layer 41. As one or more are sequentially stacked, the surface of the lens 100 may be protected to prevent contamination by static electricity and to be easily removed when contamination occurs.

The fluororesin layer 41 is preferably deposited to a thickness of 30 to 40 nm, but when deposited to a thickness of less than 30 nm, it is difficult to reduce the surface friction coefficient and adsorption power of the lens 100, causing contamination on the surface. It is difficult to prevent this, and when deposited to a thickness exceeding 40 nm, a problem in that light transmittance may be lowered may occur, so it is preferable to deposit to a thickness within the above range.

The antistatic layer 50, which is the main component of the present invention, is

As shown in Fig. 1, provided by depositing indium tin oxide on the pinhole 30, but being deposited to a thickness of 4 to 10 nm, foreign substances such as dust are prevented by suppressing the generation of static electricity. It is possible to use the lens 100 cleanly so as not to stick to the surface of the lens, that is, to prevent contamination from foreign substances.

In addition, the anti-static layer 50 is made of indium tin oxide (Indium Tin Oxide, (In ₂ O ₃ ) _0.9 (SnO ₂ ) _0.1 , ITO), which is a transparent conductive oxide, to prevent static electricity, ultraviolet rays, and An electromagnetic wave blocking effect can be additionally obtained, and heat resistance and durability can be improved.

The antistatic layer 50 is preferably deposited to a thickness of 4 to 10 nm, but when deposited to a thickness of less than 4 nm, it is difficult to control the light transmittance to increase linearly with an increase in the wavelength of light. When deposited to a thickness exceeding nm, a problem occurs in that the transmittance of light is significantly lowered, and thus it is preferable to deposit under the conditions within the above range.

The pinhole 30, which is the main component of the present invention, is

As shown in Figs. 2 to 3, pinholes 30 are spaced in at least one or more layers of the low-refractive material layer 21 and the high-refractive material layer 22 constituting the multi-layer 20. The vision correction pattern provided is formed.

As the pinhole 30 is connected by a wire in the form of a mesh, that is, connected by a connection line 31, the pinhole 30 is provided so that the connection line 31 forms a hexagonal pattern, and the connection line ( 31) Intersecting points, that is, pinholes 30 are created at each vertex of a hexagonal pattern to prevent glare by blocking and extinguishing high-order aberrations scattered by diffraction, interference, and phase phenomena when light passes through the lens. It reduces the discomfort in the near distance and makes the object look clear, reducing eye strain.

In addition, the pinhole 30 refers to a small hole such as a needle hole, and prevents glare because it allows only light necessary for the eyeball to enter, and a person with refractive errors in the eyeball such as myopia, farsightedness, astigmatism, nosight, etc. To be able to see clearly.

In addition, the connection line 31 is formed in a hexagonal pattern by connecting the adjacent pinholes 30 and the pinholes 30, so that the phenomenon of the occurrence of the pinholes 30 is maximized as the lines and lines are manufactured to have many intersections. By configuring, light entering the user's eyeball is filtered through the pinhole 30, so that the user's eyes can secure a comfortable and clear view, thereby correcting vision.

In addition, the pinhole 30 can be manufactured in various patterns, such as a triangle, a square, and a pentagon, in which the crossing points are formed, as the pinhole 30 is designed in various ways such that there are several intersection points of the connection line 31, but the triangle, square, and pentagonal As for the pattern, since the number of pinholes 30 per unit area of the lens 100 is reduced compared to that of a hexagonal pattern, the effect of filtering light is lowered, so that the connection line 31 is preferably formed of a hexagonal pattern.

On the other hand, the pinhole 30 has a diameter (D) of 0.3 mm or more, and prevents side effects such as dizziness from occurring even when worn for a long time.

In addition, when the pinhole 30 has a diameter of less than 0.3 mm, since light diffraction may be severely generated and vision may deteriorate, it is preferable that the pinhole 30 has a diameter of 0.3 mm or more. Accordingly, since the number of pinholes 30 per unit of the lens 100 is 380 to 420, the speed at which the user's eyes deteriorate can be slowed down or improved.

When the number of pinholes 30 per unit of the lens 100 is less than 380, it is difficult to block and dissipate the scattered light due to diffraction, interference, and phase phenomena generated when light passes through the lens, thereby preventing glare. Since the effect may be lowered, and if it exceeds 420, side effects such as dizziness may occur, it is preferable that the number is within the above range.

In addition, the pinhole 30 is preferably provided in at least one or a plurality of the low refractive material layer 21 and the high refractive material layer 22 constituting the multi-layer 20, but the hard material formed on the surface of the substrate After forming on the coating layer, a multi-layer 20 may be deposited thereon. More preferably, it is more preferable that the pinhole 30 is formed in the one-layer low-refractive material layer 21 or the low-refractive material layer 21 or the hard coating layer formed on the uppermost layer of the multi-layer 20.

In addition, the pinhole 30 is the rest except for the high refractive material layer 22 or the first low refractive material layer 21 or the low refractive material layer 21 formed in the uppermost layer of the multi-layer 20 When configured in a layer, the quality of the lens 100 is degraded because it affects the deposition function, or the defect rate is increased in the process of forming the pinhole 30, so that the first low-refractive-index material layer 21 or the multi-layer 20 ) It is preferable that the pinhole 30 is formed in the low refractive material layer 21 or the hard coating layer configured on the uppermost layer. More preferably, it is preferable to be configured on the low refractive material layer 21 formed on the uppermost layer of the multi-layers 20.

In addition, after forming the pinhole 30 using a laser on the hard coating layer, a multilayer 20 is deposited thereon, or after forming the pinhole 30 using a laser on the multilayer 20, the In the case of depositing the antistatic layer 50 and the super water-repellent layer 40 thereon, the evaporation material is filled in the connection line 31 having a depth by being etched with a laser, and accordingly, the height of the connection line 31 having a depth Since the height of the pinhole 30 without depth is deposited differently, the thickness difference is maintained, and accordingly, refraction occurs once, but when the connection line 31 with depth is empty, it is refracted according to the difference in the medium. Since this occurs twice, it is preferable that another material is deposited on the pinhole 30.

Meanwhile, the pinhole 30 has a first gap L1 between the connection line 31 and the connection line 31 and a second gap between the pinhole 30 and the pinhole 30 provided diagonally according to the size of the user's pupil. The interval L2, the third interval L3 between the vertically provided pinhole 30 and the pinhole 30 may be configured at various intervals, the first interval, the second interval, and the third interval of the user. If the pupil is larger than the pupil, multiple images may be felt at the same time, causing dizziness.If the pupil is smaller than the user's pupil, a dark spot may be felt in the middle of the field of view, resulting in a honeycomb-shaped afterimage, which may deteriorate the eyesight, so selectively depending on the pupil size of the user. It is desirable to manufacture.
