Problems solved by technology

However, both of these two anti-blue light protective films use traditional blue light absorbers, which only have a high absorption rate for specific wavelengths of blue light, and the overall anti-blue light effect is not good.

Abstract

The invention provides a blue light-proof protective film which comprises a functional layer; the functional layer comprises a first transparent substrate (101) and a blue light-proof layer (102) arranged on one side of the first transparent substrate (101); the blue light-proof layer (102) consists of one or at least two of nanometer tungsten oxide particles, nanometer titanium dioxide particles,nanometer silicon dioxide particles or nanometer yttrium aluminum garnet particles. The adopted blue light-proof layer with a specific material and a specific structure has relatively high blue lightobstruction rate, so that the blue light-proof protective film has a relatively good blue light-proof. The light transmittance of the blue light-proof protective film is greater than or equal to 92%,the obstruction rate to blue light with wave lengths of 380-430nm is up to 40-60%, the obstruction rate to blue light with wave lengths of 430-450nm is up to 70-80%, and the obstruction rate to bluelight with wave lengths of 450-470nm is up to 30-50%.

Description

technical field [0001] The invention belongs to the technical field of screen protective films, and in particular relates to an anti-blue light protective film. Background technique [0002] Blue light has a short wavelength and high energy, and can directly penetrate the lens and reach the retina of the fundus. Long-term blue light exposure will cause the retina to produce free radicals, leading to the decline of retinal pigment epithelial cells, which can cause retinopathy and other ophthalmic diseases. Mobile phones, computers, televisions and other electronic products are widely used, and the background light of their screens contains a lot of blue light. Therefore, filtering the blue light emitted from the screens of these products is of great significance for eye protection. [0003] The anti-blue light protective film can effectively filter out the blue light emitted by the electronic screen. There are many kinds of existing anti-blue light protective films: such a...
