Note:
1. About the eyes discomfort
The anti-peeping principle of the anti-spy film is optical shutter technology. After installation, the brightness of the screen will drop by 20% to 30%. The change in screen brightness is difficult to adapt at one time. At this time, you can increase the brightness of the screen to the appropriate brightness.
2. How to improve the anti-peep effect
There are three factors that affect the effect of the privacy film:
1) External light environment: The general anti-spy film effect is relatively weaker as the outer light is brighter.
2) Screen brightness: The general anti-spy film effect is relatively weakened as the screen brightness increases. Therefore, when using the anti-peep film, the screen brightness should not be too high, but it should not be too low, otherwise it will easily lead to eye fatigue.
3) Glossy matte: The peeping film is composed of glossy and matte surfaces. With a matte face, it can prevent glare and help protect your eyes. If the anti-spying effect is better, the light side is facing outward, so that the anti-peep effect can be improved.
