Be careful when looking at the screen

Looking at a screen continuously for a long time tires the eyes, so try to take your eyes off the screen for at least 20 seconds once every 30 minutes to look into the distance.

Rest your eyes to prevent vision loss and dry eyes.

The distance between your eyes and the screen should be about 30cm to 50cm apart. To avoid eye fatigue, do not continue to work in an unreasonable posture.

The difference between the brightness of the screen and the brightness of the surroundings can cause eye fatigue, so adjust the brightness of the screen so that it is about the same as the brightness of the surroundings, and avoid looking at the screen in a dark or very bright place.

Looking at a bright screen before going to bed can make it difficult to fall asleep, so try to avoid using digital devices such as tablet PCs that emit strong light at least one hour before going to bed.

Use tablets and computers in accordance with the rules at school and at home.

If you feel your eyes are tired, take your eyes away from the screen, look at the distance, or move your body. After looking at a screen for an hour, take a break for 10 to 15 minutes before looking at the screen again to take care of your health.
