"Anti -peeping membrane hurt eyes" appeared on Weibo hot search

Origin from an experience from a netizen

Recently, a netizen on Weibo told that he felt uncomfortable and unclear in the eyes after using the mobile phone to prevent the film, which attracted widespread attention from the Internet and appeared on the hot search. Ophthalmologists say that the decline in vision and eye discomfort are often caused by a variety of factors. It is temporarily lacking the evidence that the anti -peeping membrane will hurt the eyes, but the screen is too bright or too dark.

The netizen said that after using the anti -peeping membrane for two or three months, he had visual fatigue and discomfort to see things. After discontinuation of anti -peeping membrane, it relieved a lot. He analyzed that this is related to the decrease in the brightness and light transmission of the mobile phone after the anti -peeping membrane.

The reporter saw on the online shopping platform that there were many anti -film products, and the monthly sales volume with large sales was as high as 300,000 pieces. Compared with ordinary mobile phone membranes, the anti -peeping film is added with anti -peeping coating. It uses the optical principle in physics. It adopts the ultra -fine snail window structure, which can make the range of light reflection in the mobile phone smaller, that is, the mobile phone screen The visual angle is narrowed, so people outside the range of view cannot be seen clearly to achieve the effect of anti -peeping.

Many anti -membrane users report that after the anti -peeping membrane is pasted, the screen brightness will decrease, and the brightness of the screen needs to be brightened to achieve the original visual effect. This is because the anti -peeping structure of the interlas in the anti -peeping membrane can be reflected in a small part of the light. Therefore, the light intensity will decrease. Users will find that the screen brightness is darker than before use.

Professor Huang Zhongchen, the first affiliated hospital of Guangzhou University of Traditional Chinese Medicine, introduced that as of now, he has not encountered patients who have had eye discomfort due to anti -peeping membranes in the clinic, and did not hear similar cases when communicating with colleagues. At present, there is no research on whether the anti -enabilities 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 is not conducive to eye health. Huang Zhong committees explained that strong light, especially mobile phones and computers, can lead to eye discomfort; if the screen is too dark, the eyes will feel hard when the eyes are visually, causing visual fatigue. As for the brightness of the screen adjustment, it is suitable for different ages, different far -distance vision. It is advisable to adjust the brightness of the eyes according to their own situation.

Professor Huang Zhongchen added that there is Blu -ray in the light emitted by our mobile phone screen, and the blue light itself will hurt the eyes. Blu-ray is a high-energy visible light with a wavelength of 400-500 nanometers. Although it is not particularly dazzling, the penetrating power can directly reach the retina, damage the retina's photoresidal cells, and accelerate the oxidation of the macular region cells. It is also called the most dangerous visible light. Therefore, many mobile phone films and anti -peeping membranes have also claimed that they can prevent blue light. In fact, how big the effect is at present, there is no strong evidence.

Professor Huang Zhongchen reminds that most of the damage to the eyes is long -term, chronic, and multiple reasons, so do not be too superstitious about a certain product or too fear of a certain factor. It is always right to develop scientific eye habits and control the time and distance of mobile phones.
