My living room watched TV at a distance of 2 5 meters, and bought a 48 inch LCD TV, which hurt my ey

The distance of 48 inches is around 5 best.

In addition to projection, the reasonable viewing distance of other TVs is about 4 times the size of the color lift. For example, if it is a 20-inch (cm) TV in the Void Mountain, the viewing distance is best 4 times that of 20 inches, that is, a little more than 2 meters away from the TV screen.

The harm of excessive distance: TV has three major harms to the human body.

One is strong light and reflected light, which can cause eye fatigue. Myopia, astigmatism, cataracts, etc.

The second is positive electric ions, which affect the central nervous system, destroy red blood cells, and damage hematopoietic function.

The third is low-frequency radiation, which is the most serious and least noticeable kind of damage. It is a trace amount of ultraviolet light emitted by the picture tube inside the TV screen, which causes human cancers and infant malformations.

Therefore, watch TV carefully and not too close to the poor for a long time.

Yes, because the screen is relatively large and it is too close to see. Normally, watching TV should be in the range of three meters. This will not easily affect our vision.

I think it's better not to, even if it's in the liquid crystal, it will hurt the eyes.

Dear, it's harmful to watch it often, the radiation is large, it is recommended to change to a small one, it is enough, there is no need to be like those in the cinema.

It's too close, it's been too long to see.

It will hurt after a long time.
