Description

Technical Field

[0001] The invention belongs to the technical field of lenses, and in particular relates to a highly efficient protective photochromic myopia lens and a processing technology thereof. Background Art

[0002] At present, photochromic lenses are high-tech products that integrate multiple functions. They can not only be used as dual-purpose glasses for vision correction and sun protection, but also as protective glasses, fashion glasses, special glasses for car driving, etc.

[0003] Photochromic lenses, when exposed to sunlight, are a type of black sunglasses that can replace sunglasses. The dark lenses can block dazzling light, prevent direct strong light, and protect the eyes. In a room with soft light, photochromic lenses become transparent and colorless like ordinary lenses, and play a good bridging role in the transition between weak light and strong light. Photochromic lenses can not only darken and brighten with the intensity of light, but also absorb ultraviolet rays that are harmful to the human eye. More than 90% of skin cancers related to ultraviolet radiation occur in the area above the neck. Excessive exposure to ultraviolet rays can cause skin cancer on the eyelids and around the eyes. In addition to skin cancer, ultraviolet radiation can also increase the risk of eye problems such as cataracts and macular degeneration, and damage the immune system. Photochromic lenses can reduce these damages caused by ultraviolet rays. Photochromic lenses are suitable for people who work outdoors for a long time or on plateaus or snowy areas. They can be used as goggles. The intensity of ultraviolet rays in snowy areas, mountains, and water surfaces is much stronger than that in general areas, and can cause serious damage to the eyes. At the same time, people in these areas must ensure that their eyes have sufficient clarity. Photochromic lenses can meet this requirement.

[0004] However, currently all photochromic lenses are coated with silver halide films, which are easy to fade and oxidize, do not have a strong protective effect against stray light and strong light, and have weak transmittance. Therefore, there is an urgent need for an efficient protective photochromic myopia lens. Summary of the invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide a highly efficient protective photochromic myopia lens, which is used to avoid the problems that the previous lenses use silver halide film layers to change color, have weak photochromic effects, and have poor protective properties.

[0008] According to one embodiment of the present invention, the honeycomb protective film layer is configured as a silicon dioxide film layer, and the concave depth of the honeycomb anti-reflection unit is 20-200 nm.

[0009] According to one embodiment of the present invention, the silicon-zirconium mixed film layer is plated from a mixed powder of silicon dioxide and zirconium dioxide in a coating machine, and the mass ratio of the mixed powder of silicon dioxide and zirconium dioxide is 1:1.5.

[0010] According to one embodiment of the present invention, the fluorine-silicon mixed powder is prepared by mixing fluorine resin powder and silicone resin powder in a ratio of 1:1.

[0011] According to one embodiment of the present invention, the above-mentioned 1.75 refractive index film layer is configured as a zirconium dioxide film layer.

[0012] According to one embodiment of the present invention, the above-mentioned 1.46 refractive index film layer is configured as an aluminum oxide film layer.

[0013] The present invention also discloses a processing technology for highly efficient protective photochromic myopia lenses, comprising: Step a. Providing a resin monomer, a fluorine-silicon mixed powder, and a photochromic colorant in a ratio of 10:2:1.5, mixing them in a vacuum, and then filling them into a glass mold through a glue gun, and curing to form a substrate; Step b.
