Technical Field
The utility model relates to a protection film technical field, concretely relates to anti blue light eyeshield screen protection film.
Background
The blue light is visible everywhere in daily life, but the main source of the harmful blue light is the LED liquid crystal screen. Nowadays, the liquid crystal display screen adopts an LED backlight. Since the backlight needs the effect of white light, the blue LED is mixed with yellow phosphor to form white light. Since the blue LED is a host hardware, the blue spectrum of the white light has a peak, which creates what we said as a harmful blue light eye-hurting problem.
Studies have shown that blue light accelerates cellular oxidation in the macular region of the retina, damages visual cells, increases the risk of developing maculopathy, and leads to decreased vision, and possibly even permanent damage to vision. The mobile phone screen can generate harmful light mainly comprising blue light.
With the development of display screen technology, mobile phone and computer screens are bigger and bigger, the definition is higher and higher, and the color development is more and more gorgeous, and simultaneously, the dose of harmful light mainly based on blue light generated by the mobile phone and the computer screens is also bigger and bigger, and with more and more severe users of the mobile phone and the computer, the harm to eyes caused by long-time use of the mobile phone is more and more prominent.
In addition, the surface layer of the protective film made of common PET material has insufficient hardness and poor wear resistance and scratch resistance.
Therefore, a protective film that is resistant to blue light and abrasion and scratch is desired.
