The middle of the existing blue-light-proof mobile phone toughened film product on the market is provided with a blue-light-proof layer. The blue light prevention layer is mainly prepared by adding a blue light prevention chemical absorbent or a coating mode. But both have drawbacks.

Specifically, organic chemical dyes such as ultraviolet and blue light absorbers and light stabilizers are coated on a substrate to absorb blue light of a specific wavelength. For example, the chinese utility model patent of "a protective film for eye-protecting type touch screen for preventing blue light" of the application No. CN202020080531.7 of tianjin tianxiang electronics technology limited. The tempered film made with the blue-blocking film coated with the organic chemical dye has obvious color cast (greenish or yellowish), causes color distortion and visual fatigue, and may cause color weakness and even color blindness after long-term use. Moreover, the absorption of the current commercialized organic dye is mainly concentrated below 400nm, and the wave band with the largest damage to eyes emitted by the display screens of mobile phones and the like is 430-460nm, so that the blue light prevention film prepared by the organic dye only has the ultraviolet light prevention effect, cannot have the blue light prevention effect, and cannot protect the retina of the eyes from being damaged by blue light.

The other is formed by adopting a plurality of metal coatings with different refractive indexes. For example, the application No. CN201611030835.7 of hangzhou guest science and technology limited, the chinese patent of "a blue-light-proof film structure, a blue-light-proof lens and the application thereof", the application No. of su zhou ormas materials science and technology limited: CN201610747980.0, Chinese invention application for titled 'a blue light prevention film of a nanometer metal layer'.
