Precautions

1. High light transmittance is flicker

Many films have the words “99% light transmittance”, but the optical glass with the highest light transmittance is only 97%, and mobile phone films simply cannot achieve such a high light transmittance. If the merchant uses this as a gimmick to sell high prices, try not to buy…

2. Do not use luminous/fluorescent film

This kind of luminous film is to add fluorescent powder to the ordinary film, long-term use, the fluorescent powder is easy to inhale the human body, and it will cause damage to the skin…

3. Try not to buy matte film

Some businesses say that the frosted film feels good, but the difference between this kind of film and other films is not as big as mentioned, and it will affect the screen clarity.
