Who is more harmful to vision, watching TV or watching mobile phones?

Compared with the two, watching mobile phones is more harmful to vision for four reasons. First, the mobile phone screen is relatively small. If you want to see the content on the screen clearly, you will always stare at the screen of your mobile phone and keep a high degree of concentration. The eyes will feel tired because they are in a state of high concentration. If you use your eyes for a long time, your vision will drop sharply in a short time, causing some irreversible damage to your eyes.

Second, the distance between the eyes and the mobile phone is relatively close. Close-range light stimulation and screen radiation will make eyes ache because of too much physical stimulation from outside. Soreness is the external manifestation of internal injuries, and of course, long-term uninterrupted use of mobile phones will make this injury more obvious.

Third, mobile phones have the advantage of portability because of their small size. No matter where you are, you can take out your mobile phone to play, and the location of TV is generally fixed, so you can't see TV when you go out. This invisibly increases the time to face electronic products, and the harm will increase with time.

Fourth, the mobile phone is small, so you can fiddle with your posture at will. For example, if you feel tired, you may choose to lie down and watch your mobile phone. It's difficult to use two eyes at the same time when you are lying down and watching your mobile phone. Often one eye will be the main force to obtain video patterns, and the other eye will only play an auxiliary role. If you play with your mobile phone in the same posture for a long time, it will lead to strabismus, which is called strabismus. But you can't do TV. I often lie down and can't see the TV screen or have no place to lie down. If you feel tired, you will choose to turn off the TV and have a rest. It reduces the chance of eye error and the damage caused by radiation of electronic products.
