Do you have the habit of putting a film on your mobile phone?
Since the development of mobile phone film, many materials and versions have been derived, including toughened film, high permeability film, frosted film, anti peeping film, mirror facial mask, hydrogel film, blue light film, etc. among them, anti peeping film is jokingly called "the last privacy bottom line of contemporary migrant workers".
As we all know, the mobile phone screen under the ordinary toughened film belongs to the surrounding sharing screen. Everyone next to you knows what you are doing. When you paste the anti spying film on the screen, the mobile phone screen becomes an exclusive privacy screen. Only you who are facing the screen can see it clearly, and people on both sides will only think that you are staring at the black screen and giggling
Why does the anti peeping film prevent peeping
Here, we take the anti peeping film of mobile phones as an example to briefly explain the structural principle of the anti peeping film. A qualified peep proof film is composed of at least four parts: PE protective film layer, Ag hardening layer, PET layer and peep proof structural layer, of which the peep proof structural layer can play a major role.
Many stripe structures similar to louvers are arranged on the anti peeping structure layer. This ultra-fine micro louver structure makes the light emitted from the screen only pass through the anti peeping film at a certain angle, so that the screen information can only be seen within a certain viewing angle range with the screen as the baseline, and not beyond the viewing angle range, thus achieving the effect of "anti peeping"
Just when everyone thought that peep proof film was one of the greatest inventions in the 21st century, all kinds of information about it were frequently posted on Weibo.
Netizens broke the news: anti peeping film hurt eyes
Recently, some netizens posted on social platforms that they felt blind after using the anti peeping film for about 2 or 3 months. Everything I see is a little dark, and the cornea is often filled with red blood.
Netizens said that they do not wear glasses and are not near sighted. Their eyesight has been very good for so many years. But after using the anti peeping film for a few months, I felt that my eyes were easily tired and everything was a little dark.
The netizen said that at first, he didn't find it was the problem of the mobile phone film. Later, he tore the film and instantly felt that the whole world was clean
Many netizens said that they didn't know if they didn't watch the hot search. The original anti peeping film hurt their eyes. Of course, there are also many "sensible people" who say that not sticking a film on a mobile phone is the most basic respect for the mobile phone screen.
After the "view that peep proof films are useless", a netizen from Sichuan asked the meaning of hot search: why do you hurt your eyes?
Does the anti peeping film hurt your eyes?
According to a well-known ophthalmology Professor, there is no relevant research on whether the anti peeping film will hurt the eyes, so there is no evidence of evidence-based medicine.
However, from the perspective of eye health, the screen is too bright or dark, which is not conducive to eye health. And there is blue light in the light emitted by our mobile phone screen, which will hurt our eyes.
Blue light is high-energy visible light with a wavelength of 400-500 nm. Although it is not particularly dazzling, it has strong penetration, can directly reach the retina, damage retinal photoreceptor cells, and accelerate the oxidation of cells in the macula. It is also called the most dangerous visible light.
Therefore, many mobile phone films and peep proof films also claim that they can prevent blue light. In fact, there is no strong evidence about how effective they are. Experts suggest that it is always right to develop the habit of scientific eye use and control the time and distance of mobile phone use.
