Description

Title of the invention: a multifunctional lens

Technical field

[0001] The present invention belongs to the technical field of optical lenses, and particularly relates to an anti-blue light, ultraviolet protection, and anti-oil

Anti-reflective multi-function lens.

Background technique

[0002] The digital products commonly used today emit a lot of blue light, and the outdoor sunlight also contains a lot of blue light and ultraviolet rays and glare which are harmful to the eyes and skin.

[0003] And when we usually wear glasses, the fingers will inevitably touch the lens, causing the oil on the hands to remain on the lenses, and because the lenses generally need special syrup or equipment to clean them, people often misuse them. Paper towels to wipe the oil, this will not not wipe the lens clean, but the long-term use of the lens will be scratched by the rough paper towel, speeding up the life of the glasses.

[0004] And if the incident light is incident on the spectacle lens, the human eye does not see what it wants to see.

[0005] Although there are many kinds of lenses at present, the existing approximate glasses, sunglasses, and other protective glasses are difficult to solve the problems of oil stain, reflection, blue light, ultraviolet light, etc., and cannot meet the many functional requirements of the lens. .

technical problem

In view of the prior art, the present invention provides a multifunctional lens having anti-blue light, ultraviolet protection, oil stain resistance, and anti-reflection.

Problem solution

Technical solution

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A multifunctional lens comprising a blue light and ultraviolet resistant lens body, an oil repellent layer, and an antireflection layer between the lens body and the oil repellent layer, the antireflection layer and the lens A silver chloride coating is provided between the bodies.

[0009] wherein the lens body is a polycarbonate lens having an oxidative polymerization product of 3-hydroxyguanine ammonia.

[0010] wherein the lens body is a polycarbonate having an oxidative polymerization product of melanin, 3-hydroxyguanine ammonia Lens.

[0011] wherein the lens body is a polycarbonate lens having an oxidative polymerization product of lutein and 3-hydroxyguanine ammonia.

[0012] wherein, the antireflection layer has a thickness of 0.25 μm to 0.4 μm.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1, the multi-function lens includes a lens body 1 for preventing blue light and ultraviolet rays, an oil-repellent layer 3, and an anti-reflection layer 2 between the lens body 1 and the oil-repellent layer 3. The thickness of the anti-reflection layer 2 is 0.25 μm to 0.4 μm, and the thickness of the anti-soil layer 3 is 0.1 μm to 0.2 μm.

The material of the lens body 1 is a polycarbonate capable of blocking ultraviolet light in the range of 200 nm to 280 nm, and an oxidative polymerization product of melanin or lutein or 3-hydroxyguanine ammonia is added to the lens body 1.

[0020] A silver chloride coating is also provided, and a silver chloride coating is disposed between the antireflection layer 2 and the lens body 1.

[0021] Since polycarbonate has excellent characteristics of super impact resistance, high refractive index, light specific gravity, and greatly reduced The weight of the lens makes the lens not yellow in 3~5 years, the weight is 37% lighter than the ordinary resin sheet, and the impact resistance is 12 times higher than that of the ordinary resin.

[0022] The melanin or lutein added to the lens body 1 is a polymer formed by a series of chemical reactions of tyrosine or 3,4-dihydroxyphenylalanine. Melanin is a medium for anti-electromagnetic radiation absorption of a lens. It can effectively absorb ultraviolet light in the wavelength range of 280 nm to 400 nm and blue light in the wavelength range of 400 nm to 500 nm, and does not block the passage of light in other wavelength bands, thereby preventing the human eye from observing. The original color of the object can also prevent repeated ejection of blue light, reduce dizziness, enhance contrast, and increase the effect of visual images.

[0023] Therefore, the lens body 1 fused with melanin can achieve 100% blocking of ultraviolet rays, and blocking blue light by 98% or more, effectively reducing the damage of ultraviolet rays and blue light to the human eye.

[0024] The oxidative polymerization product of 3-hydroxyguanine ammonia added to the lens body 1 is a transparent medium which is a yellow-brown pigment synthesized in the lens of the elderly.

[0025] A silver chloride coating is attached to the lens body 1, and visible light can penetrate its molecules in the absence of ultraviolet light. The multifunctional lens is rapidly darkened under ultraviolet irradiation and is neutralized to high-intensity visible light. When the multifunctional lens is exposed to ultraviolet light of sunlight, the silver chloride molecules undergo a chemical process to make their shape. When a change occurs, the new molecular structure absorbs a portion of the visible light, thereby darkening the lens and neutralizing the high-intensity visible light to protect the vision. The number of molecules whose shape changes will change with the intensity of the UV light. When you come indoors, the multi-function lens is exposed to ultraviolet light, and the silver chloride molecules will undergo corresponding chemical reversal changes and quickly return to the original structure. Whether it is positive or negative, the whole process takes place very quickly.

The antireflection layer 2 is obtained by plating a high-purity metal oxide material such as titanium oxide or zirconium oxide on the surface of the lens body 1 by an evaporation process, thereby obtaining a good antireflection effect.

[0027] The oil-repellent layer 3 is formed by plating a fluoride on the anti-reflection layer 2 by a vacuum plating process, covering the porous anti-reflection layer 2, and reducing the contact area between the water and the oil and the lens, making the oil and water droplets difficult. Adhered to the surface of the lens to prevent oil stains.

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of within the technical scope disclosed by the present invention. Changes or substitutions are intended to be included within the scope of the invention. Therefore, the scope of protection of the present invention The scope of protection of the claims shall prevail.
