Allochroic polarized light night vision lens

Abstract

The invention relates to an allochroic polarized light night vision lens. The allochroic polarized light night vision lens comprises a TAC white spectrum layer and a polarized light sheet compound on the TAC white spectrum layer, and is characterized in that an allochroic layer is compound on the polarized light sheet, a filtering layer is compound on the allochroic layer, TACHC film is compound on the filtering layer, the allochroic layer is composed of TAC film, PVC film and TAC film in sequence, and the filtering layer is formed by compounding a trititanium pentoxide layer, a silicon dioxide and a zirconium dioxide layer. The allochroic polarized light night vision lens can effectively filter out infrared light and blue light in light rays through the filtering layer, and accordingly the effect of protecting eyes is achieved.

Description

technical field [0001] The invention relates to a sun lens, in particular to a color-changing high-definition sun lens. Background technique [0002] White light in nature is a mixture of blue light, green light, and yellow light. Among them, green light and yellow light have less energy and are less irritating to the eyes, while blue light has short wavelength and high energy, and can directly penetrate the lens and reach the retina of the fundus. It plays a certain protective role, especially for those who stare at the electronic screen for a long time. [0003] Infrared light is also called infrared light, which belongs to invisible light. Because the eyeball contains a lot of liquid, these liquids have an absorption effect on infrared light with a wavelength of less than 1.5 microns. The fluid in the lens reacts by absorbing short-wave infrared light, causing lesions that cloud the lens and cause cataracts. [0004] At present, general sun lenses have the following di...

AI Technical Summary

Problems solved by technology

[0004] At present, general sun lenses have the following disadvantages: 1. Poor anti-red light performance and anti-blue light performance; 2. When worn at night, the visual effect is poor, and the intensity of the high beam cannot be effectively reduced, which is likely to cause traffic accidents; 3. When wearing at sea or snow, there will be glare
