Therefore, every hour of reading and writing, you should go outdoors for 10 minutes, which is an effective way to eliminate eye muscle fatigue and prevent myopia.

When reading and writing at night, the lights should not be too dim, shaking or dazzling. The light should come from the left front to avoid shadows blocking the line of sight. Don't read or write in strong light (such as sunlight or dazzling light) or in the shadow of flowers to reduce the adjustment burden of intraocular lens and ciliary body.
4, watching TV for too long: TV is a dynamic picture, watching it for too long, it is most likely to lead to eye muscle fatigue and myopia. Therefore, watching TV should not be too long, generally should be controlled within 2 hours, and rest for at least 5 minutes every 30 minutes to give your eyes a rest. The distance to watch TV should be appropriate, generally 2 meters away, and the angle should not exceed 45 degrees. In the room watching TV, there should be a certain brightness of the lights. You can turn on a small light, but don't direct the light at the screen or eyes. It's best to put it in the back or next to it. When debugging the TV, the jumping picture on the TV screen is very harmful to your eyes. Please close your eyes to avoid irritation.
