One of the causes of myopia for children is that children watch TV too much and the distance from seat to the big screen TV is not appropriate.

As recommended, the distance from seat to TV screens are not too close or too far. If a 14 inch screen, you should sit 1.6 m; with 22-inch machine, the appropriate distance is 2.4 m. The distance required is 1.8 m with 16-inch screen, 2 m with 18 inch screen and 2.2 m with 20 inch screen.

Also, when watching TV, room TV set must have enough light, tender to create a comfortable, pleasant. During the day, to lower the window blinds to enhance the sharpness of the image. At night, the lights should turn to a soft image, easy to view.

With color TV, to adjust to not light too (not dazzling), not too dark. Images should be clear, not like the color, making the viewer feel good. There are new so no harm to the eye, to health. The height of the television center must equal or slightly lower than eye level.

Do not watch TV more than 2-3 hours continuously will cause eye fatigue, increases feeling tired, cause sleep problems, headaches ... Just watch out next after a walk or relax for a while.
