Correct way:

  1. If you can use voice input, you will type less, and if you can use two hands, you will use less one hand.

  2. If you use your mobile phone for more than half an hour, you need to stop and relax.

  3. Ensuring full rest of fingers and wrists can relieve pain.

Lying and watching mobile phones may cause myopia.

  1. Pay attention to posture, don’t lie down or look at your cell phone on your stomach.

  2. The best distance between eyes and mobile phones is about 30cm.

  3. Move every half hour, look out into the distance, close your eyes and rest.
