Netizens Xiaobi said that after almost half a year of anti -peeping membrane, the screen always felt that the screen was not bright, and the eyes were sour. I feel that the screen of the mobile phone is super clear. "

Some people say that the brightness of the mobile phone after the film becomes lower, and the brightness of the phone needs to be adjusted very high to see the content on the screen, which also indirectly increases power consumption.

Merchants say that injury is misunderstanding

The product starts from 25 degrees from the side

The reporter noticed that there are not a few anti -spy -films products on the shopping platform. Taking "anti -peeping membrane" as keyword search, a total of 250,000 search results showed that the price ranged from 9.9 yuan to 250 yuan.

The merchant claims that "eye protection, super clear the eyes, not hurting the eyes, not shaking the eyes", "fingerprint second solution". From the perspective of sales, the maximum monthly sales reached 100,000 orders.

For the principle of anti -peeping, the merchant introduced that there is a special layer of spray layer on the mobile phone film. Through the louver -like louver, it is introverted in the steel layer in the form of leaves. In the room, you can see the outside scene, closing the window to block the outside of the outside world, and cannot see the outside scene.

The merchant explained that the anti -peeping membrane is the same. When the front view is open to the window, you can see the screen content. When viewed on the side, it is the window closing state. It will reflect from other angles. While realizing positive viewing, the voyeur vision at a certain angle of the partial side is achieved to achieve the purpose of protecting privacy.

There are also customer service introductions that the anti -peeping membrane starts from 25 degrees from the side, which can effectively protect personal privacy.

Some merchants also admit that compared with ordinary membranes, the mobile phone will indeed be darker after the anti -peeping membrane is pasted, and it can be adjusted by raising the brightness of the mobile phone.

At the same time, the merchant stated that there was a misunderstanding of the statement of anti -eye injury, and "the anti -peeping membrane does not hurt the eyes."

Whether the anti -peeping membrane hurts the eyes

Doctor response

The reporter learned that because of the problems of eyes, mobile phones, and personal privacy are closely related to daily life, whether the anti -peeping membrane hurts the eyes, it has become a topic that everyone is more interested in.

In an interview with the media, Professor Huang Zhongchen, the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, introduced that there is no research on whether the anti -eye film will hurt the eye, so there is no evidence for evidence -based medicine. However, from the perspective of eye health, the screen is too bright or too dark.

Huang Zhong committees explained that mobile phones, computers, etc. are overwhelmed, which will cause eye discomfort; if the screen is too dark, the eyes will feel difficult when the eyes are visually, causing visual fatigue. 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. Many mobile phone films and anti -peeping membranes claim that they can prevent blue light and lack strong evidence.

Wang Shulin, deputy chief physician of the Ophthalmology Department of Henan Provincial People's Hospital, told reporters that as the merchant said, the anti -peeping membrane posted on the mobile phone screen uses a grating technology similar to a clover window to play a certain role in anti -peeping and protecting personal privacy.

At the same time, Wang Shulin emphasized that because the anti -peeping membrane blocks the light of a part of the mobile phone screen, it is really easier to cause visual fatigue after watching the time for a long time.
