DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] In order to more clearly describe the embodiments of the present invention and the technical solutions of the prior art, the present invention will be briefly described below in combination with the accompanying drawings and the embodiments or the description of the prior art. It is clear that the structural description in the following accompanying drawings is only a part of the embodiments of the present invention, and those skilled in the art can obtain other accompanying drawings from these accompanying drawings without creative work. It should be noted that the description of these embodiments is for the purpose of helping the understanding of the present invention, and does not limit the present invention.
[0017] Working Example The present embodiment provides a method for manufacturing an eye-protecting lens, the method including the following manufacturing steps:
[0018] 100) The immersion method is used to treat eyeglass lenses with blue light blocking and ultraviolet blocking agents.
[0019] The method includes the steps of immersing a spectacle lens in a mixed solution containing an ultraviolet absorbing agent containing methacrylate and styrene in a mass ratio of 13:37 and a blue light absorbing agent, and performing blue light cut and ultraviolet cut treatment on the spectacle lens, the mass ratio of the blue light absorbing agent to the ultraviolet absorbing agent in the mixed solution being 1:1, the temperature of the mixed solution when immersing the spectacle lens is 30 to 50 degrees, and the immersion time is 30 to 45 minutes. The immersion-treated spectacle lens has good ultraviolet (300 to 400 nm) absorption ability and blue light (380 nm to 440 nm) absorption ability.
[0020] 150) Before the optical coating process is performed on the eyeglass lens, a hardening process is performed, and the specific operation of the hardening process is as follows.
[0021] The eyeglass lens (a spectacle lens with a refractive index of 1.5 and a spectacle lens with a refractive index of 1.69 are relatively commonly used) is immersed in a solvent containing a hardening liquid, and then placed in an oven at 90 to 110 degrees (for example, 90 degrees, 100 degrees, or 110 degrees, etc., can be adjusted within this range according to the actual situation) for 4 to 5 hours (for example, 4 hours, 4.5 hours, or 5 hours, etc., can be adjusted within this range according to the actual situation). This temperature and time baking provides the optimal hardening effect of the eyeglass lens; if this condition is not reached, the surface hardness of the eyeglass lens cannot achieve the requirements; if this condition is exceeded, the surface hardness of the eyeglass lens is too high, the eyeglass lens is too brittle, and the hardened layer on the surface of the eyeglass lens is easy to tear. The coating layer thickness of the hardened layer on the concave and convex surfaces of the eyeglass lens is 3 to 5 um (for example, 3 um, 4 um or 5 um, can be adjusted within this range according to the actual situation).
[0022] 200) An optical coating process is performed on eyeglass lenses using a deposition method.
[0023] Before deposition, the eyeglass lens is ultrasonically cleaned and then placed in an oven to dry for 3.5-4.5 hours (for example, 3.5 hours, 4 hours or 4.5 hours, which can be adjusted according to the actual situation within this range) to dry the eyeglass lens, and the dried eyeglass lens is the eyeglass lens to be coated. Only under these baking conditions of the eyeglass lens can the moisture in the material of the eyeglass lens be sufficiently dried, and when the eyeglass lens is coated, the bond between the coating film layer and the eyeglass lens is the most stable, and if the baking time is insufficient or too long, it will affect the stability of the bond between the film layer and the eyeglass lens.
[0024] Before starting coating, the eyeglass lens to be coated is set on the coating jig and then sent into the coating furnace, where the coating environment is 2.0*10 -5 The vacuum is drawn to TOOR, and the eyeglass lens to be coated is first ion-cleaned to strengthen the adhesion of the film layer, and then coating is started. Six optical film layers of different thicknesses are stacked on the concave and convex surfaces of the eyeglass lens in order so that the optical film layers transmit the visible wavelength range of light irradiation of the eyeglass lens to 630-750 nm. After coating, the surface reflection of the eyeglass lens is reduced by 70-80%, and the transmittance of the eyeglass lens is improved by 2-3% on one side. Only when the thickness of the optical film layer to be coated is designed to be six layers, can the optimal effect be achieved in the reduction of reflectance and transmittance after coating; too few or too many film layers will affect the effects of reflectance and transmittance.
[0025] Specifically, the six optical film layers having different thicknesses are laminated in order on the concave and convex surfaces of the eyeglass lens so that the total thickness of the six optical film layers is 161 nm to 205 nm. a first optical film layer having a thickness of 20 nm to 30 nm and made of silicon monoxide; a second optical film layer having a thickness of 8 nm to 10 nm and made of titanium pentoxide; a third optical film layer having a thickness of 8 nm to 10 nm and made of silicon dioxide; a fourth optical film layer having a thickness of 50 nm to 65 nm and made of titanium pentoxide; a fifth optical film layer having a thickness of 60 nm to 70 nm and made of silicon dioxide; It includes a sixth optical film layer having a thickness of 15nm to 20nm and made of AF (Anti-fingerprint vacuum coating) material that enhances the anti-fouling performance of the surface.
[0026] This embodiment provides a lens for protecting eyes manufactured by the manufacturing method according to the above embodiment.
[0027] This embodiment provides eyeglasses including an eyeglass frame and a lens for protecting the eyes, which is manufactured by the manufacturing method of the above embodiment and attached to the eyeglass frame.
[0028] The eye protection lens and glasses equipped with the eye protection lens manufactured by the manufacturing method of the present invention have excellent blue light blocking and ultraviolet blocking effects, effectively preventing eye damage caused by light and reducing eye irritation caused by reflected light on the surface of the eyeglass lens, and effectively relieving visual fatigue of the eyes. In addition, the transmittance of the eyeglass lens can be increased, and the manufactured eye protection lens can achieve a high transmittance of more than 96%, allowing the eyes to see more clearly and more comfortably, and further protecting the eyes. The transmitted visible wavelength range of the light irradiation of the lens of the present invention is 630 to 750 nm, so that the retinal cells of the eye are stimulated by low-energy red light of 630 to 750 nm, activating the retinal cells and generating photobiological reactions, strengthening the retina and sclera, expanding the blood vessels of the choroid, thickening the vascular walls, shortening the eye axis, improving naked eye vision, and promoting blood circulation, resulting in healthier vision.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
