Let's learn about the principle of blue light and anti-blue light tempered glass film.
The blue light is the light with a wavelength of 400-500 nm, which is a kind of visible light with short wave and high energy. It can directly penetrate the lens and reach the retina. In the era of smart phones, people spend more time staring at the screen of mobile phones. However, mobile screen, LED and computer screen lights will produce a lot of blue light, which will bring harm to people's eyes and hands, stimulate brown pigment, make skin produce macula and freckles, deepen the degree of myopia, and produce visual fatigue, and also is not conducive to sleep. For this, anti-blue ray tempered glass is used for making mobile phone tempered films.
The anti blue light tempered film for mobile phone is a kind of eyesight protection film developed against blue light radiation. It adopts the blue light blocking technology to effectively absorb and convert blue light, thus realizing the purpose of eyesight protection.
