In recent years, large-screen and full-touch screen series mobile phones have gradually occupied the dominant position in the mobile phone industry, and the use of mobile phone screen protective films has become more and more widespread.

At present, there are many kinds of mobile phone films on the market, mainly blue film, frosted film, mirror film, etc. There are mainly 4 kinds of production materials: PP, PVC, PET, ARM.

Mobile phone films made of PET and ARM have better light transmittance. A mobile phone film with poor light transmittance will make it very difficult for people to use the mobile phone and increase eye fatigue.

Especially when the screen is under-illuminated, it is difficult to see the fonts, the eye ciliary muscles will always be in a state of tension, the lens continues to maintain a large convexity, and the eyes are easily tired due to over-adjustment.

The mobile phone film is mainly to protect the screen, and the wear of the mobile phone film is inevitable, so we should choose some mobile phone films with wear resistance when choosing mobile phone films. Generally speaking, the higher the wear resistance of the mobile phone film, the higher the smoothness.

When the phone film has scratches or bubbles, it should be replaced immediately, otherwise it will affect the clarity and cause eye fatigue.

The blue light film on the market has always been favored by consumers, so can blue light film really prevent blue light?

The experiment results of the curiosity laboratory co-organized by the Hangzhou Association for Science and Technology show that the anti-blue light film has almost no resistance to blue light.

At the same time, some experts said that blue light's damage to the human body mainly comes from two points. One is high intensity, such as LED lighting. The light contains a large amount of blue light that may cause damage to the retina, but the blue light emitted by mobile phones can damage the retinal tissue far. Not up to the magnitude of the hazard.
