The degree of damage to the eyes from computers and reading books depended on many factors such as frequency of use, screen size, light intensity, and so on. Generally speaking, staring at a computer screen for a long time may cause more damage to the eyes because the computer screen is usually larger than the reading screen and the light is often dimmer. In order to reduce eye fatigue and damage to the eyes, it is recommended to rest for 5-10 minutes every hour, stay away from the computer screen and look at distant objects, and keep the room well lit and bright. In addition, you can also take some measures to reduce eye fatigue, such as adjusting the brightness and contrast of the computer screen and using anti-blue glasses. At the same time, regular eye rest, eye massage and hot compress can also help relieve eye fatigue.
