Watching television in the dark causes a lot of damage to the eyes because the human eye always works well in white light, that is, it can be seen clearly in white light. According to doctors, watching television in the dark can cause two types of problems. First , the intense bright light of the television has a detrimental effect on the eyes in the dark. This intense light inside the eye reflects internally. This damages the retina of the eye. Second , the light vibration of the television screen is much higher in the dark. The eyes get tired. So you should not watch television in a dark room. To avoid its harmful effects, you should watch television at least 3-4 meters away from the bright room.
