Description

Anti-yellow light health lens

technical field

The utility model relates to an anti-yellow light health-care lens, which is suitable for making health-care sunglasses.

Background technique

Sunglasses, also known as sun visors, as the name suggests, are used as sunshades to block light. In sunlight, the human eye will actively adjust the pupil size to adjust the luminous flux of the eyeball, but when the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, it is necessary to use sun visors to block the sun and reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation.

Existing sunglasses, the lenses can only protect against ultraviolet rays. The product can block ultraviolet rays with a wavelength below 420nm, but cannot block light with a wavelength of 420nm. Yellow light has a wavelength of 580-600nm. Yellow light has no direct effect on the body in the short term. However, long-term exposure will cause vision loss, eye fatigue, and color weakness.

Therefore, the inventor specially improves the lens structure and develops a kind of anti-yellow light health care lens, and this case arises from it.

Utility model content

The purpose of the utility model is to provide an anti-yellow light health care lens, which has a simple structure, can effectively block yellow light and ultraviolet rays, and protect the eyes.

In order to achieve the above object, the solution of the present utility model is:

An anti-yellowing health-care lens is composed of a lens base material, an anti-ultraviolet coating and an anti-yellow coating, and the anti-ultraviolet coating and the anti-yellow coating are formed on the surface of the lens base.

An anti-yellow coating is firstly formed on the front surface and the back surface of the lens substrate, and an anti-ultraviolet coating is formed on the surfaces of the two anti-yellow coatings.

An anti-yellowing coating is formed on the front surface of the lens substrate, and an anti-ultraviolet coating is formed on the back surface of the lens substrate.

The thickness of the anti-ultraviolet coating is 3-5 microns.

The thickness of the anti-yellowing coating is 3-5 microns.

The anti-ultraviolet coating is the UV-300 toner of Taiyi International Co., Ltd.

The anti-yellowing coating is Taiyi International Co., Ltd. WL-580 dyeing solution.

The coating solid content of the anti-yellowing coating is 20wt%, the solid particle diameter is 20-30nm, and the pH value is 4-7.

After adopting the above scheme, the utility model has a simple structure. Compared with the existing sunglasses lens, an anti-yellow coating is added, which can effectively block the yellow light, make the product spectrum reach 430-580nm, and the maximum transmittance of visible light reaches 90%. , not only has the beauty of ordinary sun lenses, but also has a clear field of vision, and also protects the eyes, avoids the damage of yellow light to the eyes, prevents glaucoma, cataract and optic atrophy, and there is a lot of room for the future market.

The utility model is described in detail below in conjunction with accompanying drawing and specific embodiment.

Fig. 2 is a schematic structural view of Embodiment 2 of the utility model.

Label description

Lens substrate 1, anti-ultraviolet coating 2, anti-yellowing coating 3.

Detailed ways

As shown in Fig. 1 to Fig. 2, an anti-yellowing health-care lens disclosed by the utility model is composed of a lens base material 1, an anti-ultraviolet coating 2 and an anti-yellowing coating 3 to form a composite structure.

An anti-ultraviolet coating 2 and an anti-yellowing coating 3 are formed on the surface of the lens substrate 1 . During processing, the anti-ultraviolet coating 2 and the anti-yellowing coating 3 can be directly formed on the lens substrate 1 by vacuum coating, or soaked first and then the coating is cured to make the anti-ultraviolet coating 2 and the anti-yellow coating A photocoat 3 is attached to the lens substrate 1 .

Specifically, as shown in Figure 1, an anti-yellow coating 3 is first formed on the front surface and the back surface of the lens substrate 1, and an anti-ultraviolet coating 2 is formed on the surfaces of the two anti-yellow coatings 3 to form a Five-layer composite structure; or as shown in Figure 2, an anti-yellowing coating 3 is formed on the front surface of the lens substrate 1, and an anti-ultraviolet coating 2 is formed on the back surface of the lens substrate 1, forming a three-layer composite structure.

Wherein, the anti-ultraviolet coating 2 adopts UV-300 toner of Tai-One International Co., Ltd. The thickness of the anti-ultraviolet coating 2 is 3-5 microns. The optimal thickness of the anti-ultraviolet coating 2 after drying is 0.01 micron. The anti-yellowing coating 3 adopts WL-580 dyeing solution of Taiyi International Co., Ltd. The coating solid content of anti-yellow light coating 3 is 20wt%, and solid particle diameter is 20-30nm, and pH value is 4-7, and the thickness of anti-yellow light coating 3 is 3-5 micron, and the anti-yellow coating formed after drying The optimum thickness of the photocoat layer 3 is 0.01 micron.

The above is only a preferred embodiment of the present utility model, and is not a limitation to the scope of protection of the present utility model. Any deduction or replacement of the above-mentioned embodiment that does not have an essential difference with the technical solution of the present utility model should be regarded as Fall within the protection scope of the present utility model.
