The harm caused by mobile phone films cannot be ignored!

Today's smartphones are like miniature computers. No matter where you go, you can always see people playing with their phones or using screen protectors. But can a screen protector really protect your phone? In fact, using a screen protector can actually affect your eyesight.

Ms. Tian has recently become addicted to mobile games. Due to work reasons, she has to take the subway frequently every day. Including the time to and from get off work, she spends nearly 5 hours on the subway every day, during which time she spends almost all her time playing with her mobile phone. Many mobile games require frequent touch of the screen, so the mobile phone film has many scratches. Due to my busy schedule, I have no time to replace it. It was not until last week that I experienced eye swelling and pain. I went to the hospital and found out that it was related to the influence of the mobile phone film.

"There are quite a few mobile phone users like Ms. Tian among the patients we see in our department. I don't use a screen protector on my phone because it will refract the light from the screen and increase visual fatigue. Especially if the screen protector has a lot of scratches, it will cause greater harm to eye health!" Xia Chengzhi, director of the Department of Ophthalmology at Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, said that screen protectors are only a "booster" that harms eye health. The most important reason is the long-term close-up use of the eyes when using a mobile phone. This harm to eye health is much greater than watching TV, using a computer, reading and writing at close range!

Especially after applying the film, if it is not replaced for a long time, the messy scratches will make the phone screen display look more laborious, the ciliary muscles of the eyes are often in a tense state, the lens continues to maintain a large tension, and the health of the eyes is more easily damaged. It is recommended that you pay attention to resting your eyes after using your mobile phone for more than half an hour. At this time, it is okay to apply some preservative-free eye drops. It is best to move your eyeballs and increase the time of long-distance use of your eyes to better maintain your eyes.

Mobile phone screen protectors are only used to protect mobile phones, but if used for a long time, various scratches will appear on the screen protector, which will make it more strenuous for your eyes to look at the phone. Therefore, it is best to change the screen protector from time to time to reduce the pressure on the eyes.
