The privacy filter has the effect of protecting personal privacy and preventing others from peeping. The visible area is 60 degrees, that is, only one black and white can be seen from the left and right sides of 30 degrees. The surface is strengthened, scratched, and wear resistant, and the hardness reaches 4-5H. However, after many people use the anti-peep film, they will feel uncomfortable in the eyes. Does the privacy filter really affect our vision?

　　1. After using the privacy filter, the screen will be dark!

　　The anti-spy film is based on the ultra-fine louver optical polarization principle, which blocks part of the light. All the screens will look dull and blurry! This is the main reason why our eyes are uncomfortable after putting on the peeping film.

　　2. Some privacy filter will be streaked after being attached

　　Some anti-spy film will appear streak, this phenomenon is due to the fact that the die-cutting alignment is not good at the factory, and the angle is not set when the die-cutting. This also has a certain influence on our eyes.

　　What should I do if I feel uncomfortable after putting on the peeping film?

　　Long-term fatigue of the eyes, or looking at the state of flowers, is likely to cause a decline in eyesight. Regardless of the film attached, if you stare at the screen for a long time, it will have an effect on the eyes. Therefore, it is still necessary to reduce the time of using the eyes at close distances, and look at the distance in time to make the eyes relax!
