Mobile phones have become inseparable objects in everyone's lives. On the subway and buses, the "low -headed people" can be seen everywhere. Everyone uses mobile phones to swipe news, send information, pay ... and in this process, how to not let people around you see the content on their mobile phones is a concern.

As this kind of demand is increasing, the anti -peeping membrane has appeared. Like other mobile phone films, a light post, the people next to them cannot see the content on the mobile phone. It does not affect the use, but also guarantees that privacy content is not seen.

Recently, the topic of#anti -peeping membrane injury to the eye rushed to the hot search. A netizen described that after using the anti -peeping membrane for two or three months, eye fatigue and other discomfort occurred, and there were black shadows to see things. Many people dare not use anti -peeping membrane again.

How much harm can the small anti -anti -membrane hurt the eyes? Does ordinary mobile phone film affect? Look at it together.

Why can't others see the screen?

Anti -peeping membrane uses the micro -louver optical technology of the anti -peeping structure layer, which is similar to the principle of the louver window in our usual home or office. You can use the adjustment angle to realize different visual cover. Users can see the screen content when reading positive reading From other perspectives, you can only see the dark picture, so as to prevent others from peeping and protect the privacy of users.

Will the anti -peeping membrane really hurt the eyes?

Many people feel that the eyes are dry and more fatigue after using the anti -peeping membrane. Some people also find that the degree of myopia has deepened. So, is it really caused by the anti -peeping membrane?

At present, there is no direct evidence that the anti -peeping membrane can cause damage to the eyes. However, due to the existence of the louver structure in the anti -peeping membrane, the light emitted by the screen cannot enter the human eyes, which will make the screen look darker.

If you look at the dark screen with a darker light for a long time, it may cause ciliary muscle spasm. Over time, it may cause visual fatigue and dry eyes. For young people who are developing in the eyeball, it may also accelerate the development of myopia.

Therefore, although the harm of the anti -spy membrane to the human eye has not been confirmed by scientific research, the screen brightness caused by the anti -peeping membrane decreases, which may cause various discomfort symptoms of the eyes.

Does other mobile phone films affect the eyes?

In addition to the anti -peeping membrane on the market, the screen film also includes steel film, scrub film, diamond membrane, mirror mask, etc.

The quality of the quality of the quality is good, the light transmission is good, it has little effect on the light of the screen, and the damage to the eyes is also small.

The surface of the scrub film can be relatively reduced through scrub processing. Although the fingerprint residue on the screen is relatively poor, the light transmission rate is worse than the ordinary tempered film, but the damage to the eyes is also minimal under the situation of reasonable use.

However, if the quality of the film is poor, the film is not fully fitted with the screen, and even when there are some scratches, the light transmission and sharpness of the screen will be reduced. The damage will be greater than usual.

The screen brightness is darkened

Will it reduce the damage to the eyes?

The light emitted by screens such as mobile phones and computers contains short -wave blue light that has harmful effects on human eyes. For a long time and large dose of short -wave blue light into the human eye, it will cause free radicals to generate the retina. Imagine damage.

If the electronic screen is unreasonable, and the brighter screen brightness, it will undoubtedly increase the damage to the eyes by the short wave of blue light. However, if the screen brightness is adjusted too dark, the eyes are difficult to see the content on the screen clearly, which may cause visual fatigue.

Therefore, the brightness of the screen cannot be too bright nor too dark. It should be adapted to the brightness of the external environment, and the most comfortable screen brightness with the eyes should be selected. At the same time, we must also avoid long -term and under dark environments to avoid aggravating the effect of the screen on the eyes.
