Technical Field
[0001] The utility model relates to the technical field of eyeglass lenses, in particular to a composite structure of an anti-glare driving lens. Background Art
[0002] As we all know, glare is an undesirable lighting phenomenon that occurs when the brightness of the light source is extremely high or when there is a large difference in brightness between the background and the center of the field of vision. Glare is very harmful to the eyes.
[0003] The existing anti-glare lenses are made by keeping the perspective of the center point of the lens unchanged on the basis of the special TAC polarized yellow film, and then modulating and dyeing it with organic chemicals, and then coating it on the front and back. Among them, the special TAC polarized yellow film is mainly composed of a yellow bottom layer, a PVA film middle layer and a yellow top layer. The yellow top layer is made of TAC material, and the yellow bottom layer and the lens substrate are made of the same material. The dyeing occupies 1 / 3 of the lens body from top to bottom.
[0004] The specially structured TAC polarized yellow lens has a clear yellow bottom film, which makes the lens have a higher perspective. The brown dye covering the upper end of the lens can filter out a lot of blue light, increase brightness, and improve visual contrast and clarity. However, when wearing existing anti-glare lenses, if there is glare in front, you can only see through the upper part of the lens. When the glare passes, the human eye can maintain a normal horizontal line of sight.
[0005] Therefore, the inventor conducted in-depth research based on the eye usage habits while driving, and specifically targeted the damage caused by glare, and developed and designed anti-glare lenses suitable for use in driving, which resulted in the present case. Utility Model Content

[0014] The thickness of the nano antibacterial layer is 25-30nm.
[0015] The thickness of the waterproof layer is 8-15nm, and the thickness of the oil-proof layer is 8-15nm.
[0016] After adopting the above scheme, the utility model does not need to make special TAC polarized yellow films for different substrates as in the prior art; the UV420 blue light absorption layer is used to block 400nm~420nm high-energy visible light on the basis of blocking ultraviolet rays; the 585nm yellow light absorption layer can absorb about 55% of 585nm visible light; the color-changing strengthening layer has an all-weather color-changing effect, and can change color in real time according to the change of ultraviolet intensity to protect the eyes; the OAR film layer can reduce the reflected light on the back of the lens to the eyes, making the vision clearer; the nano-antibacterial layer is used to make the inner surface of the lens have an antibacterial effect to prevent accidental bacterial and fungal cross-infection and infection of the eyes; the waterproof layer and the oil-proof layer are used to play a role of waterproof and oil-proof, so that the surface of the lens is kept clean, pollution is avoided, and the vision is clear without marks.

When encountering glare, there is no need to deliberately move the line of sight, and you can observe in all directions, with a wider field of vision and clearer vision. It can effectively prevent eye discomfort caused by glare, reduce eye fatigue, and ensure driving safety.
