DETAILED DESCRIPTION

[0029] Embodiment:

[0030] The embodiment provides a preparation method of an eye-protecting lens, which comprises the following manufacturing steps:

[0031] 100) The eye-protecting lens is treated by the soaking method to resist blue light and ultraviolet light.

[0032] The eye-protecting lens is soaked in a mixed solution containing a blue light absorber and an ultraviolet light absorber to complete the treatment of the eye-protecting lens to resist blue light and ultraviolet light; the ultraviolet light absorber comprises methyl methacrylate and styrene in a mass ratio of 13:37; the mass ratio of the blue light absorber and the ultraviolet light absorber in the mixed solution is 1:1, the temperature of the mixed solution is 30-50 degrees when the eye-protecting lens is soaked, the soaking time is 30-45 minutes, and the eye-protecting lens treated by the soaking treatment has good functions of absorbing ultraviolet light (300-400 nm) and absorbing blue light (380 nm-440 nm).

[0033] 150) The eye-protecting lens is hardened before optical coating treatment, and the specific operation is as follows:

[0034] The spectacle lens (commonly used are spectacle lenses with a refractive index of 1.5 and spectacle lenses with a refractive index of 1.69) is immersed in a solvent containing a hardening solution, and then an oven at 90-110 degrees (such as 90 degrees, 100 degrees or 110 degrees, which can be adjusted according to actual conditions within this range) is used for 4-5 hours (such as 4 hours, 4.5 hours or 5 hours, which can be adjusted according to actual conditions within this range). The spectacle lens is best hardened under this temperature and time, and if the conditions are not met, the surface hardness of the spectacle lens cannot meet the requirements, and if the conditions are exceeded, the surface hardness of the spectacle lens will be too hard and brittle, and the hardened layer on the surface of the spectacle lens will easily crack. The coating thickness of the hardened layer on the concave and convex surfaces of the spectacle lens is 3-5um (such as 3um, 4um or 5um, which can be adjusted according to actual conditions within this range).

[0035] 200) The spectacle lens is treated by optical coating using evaporation method:

[0036] Before evaporation, the spectacle lens is cleaned with ultrasonic wave and dried in an oven for 3.5-4.5 hours (such as 3.5 hours, 4 hours or 4.5 hours, which can be adjusted according to actual conditions within this range). The spectacle lens is baked and dried, and the baked and dried spectacle lens is the spectacle lens to be coated. After the spectacle lens is baked under this condition, the moisture in the material of the spectacle lens can be fully baked, and the coating layer and the spectacle lens are most stable when the spectacle lens is coated.

[0037] Before starting the coating, the spectacle lens to be coated is loaded into a coating fixture, and after loading, it is sent into a coating furnace. The coating environment is vacuumed to 2.0*10 -5 TOOR, the ion cleaning of the spectacle lens to be coated can enhance the adhesion of the coating layer, and then the coating is started. Six layers of optical coating layers with different thicknesses are designed on the concave and convex surfaces of the spectacle lens, respectively. The optical coating layer makes the wavelength range of the spectacle lens for light transmission and perspective to be 630-750nm. The surface reflection of the coated spectacle lens is reduced by 70-80%, and the single-side transmittance of the spectacle lens is increased by 2-3%. When the thickness of the optical coating layer is designed to be 6 layers, the reflectivity and transmittance of the coated spectacle lens can achieve the best effect. Too few or too many layers will affect the reflectivity and transmittance.

[0038] Specifically, six layers of optical coating layers with different thicknesses are designed on the concave and convex surfaces of the spectacle lens, respectively. The total thickness of the six layers of optical coating layers is 161nm-205nm, and the six layers of optical coating layers include:

[0043] The fifth optical film layer has a thickness of 60-70 nm and is made of silicon dioxide;

[0044] The sixth optical film layer has a thickness of 15-20 nm and is made of an AF layer (AF, full name Anti-fingerprint, short for Anti-fingerprint vacuum coating), which can improve the surface anti-fouling performance.
