Watching TV with fluorescent lamp is harmful to health? Pray for the great gods.

When watching TV, many people are used to turning on fluorescent lamps, thinking that this can soften indoor light and protect their eyesight. But in fact, watching TV with fluorescent lamps will not only protect your eyesight, but also damage your eyesight. Expert analysis: In human eyes, there are two kinds of visual cells: cone and rod. Cone cells are specifically responsible for seeing things during the day or in bright light; Rod cells are responsible for seeing at night or in poor light. Rod cells contain rhodopsin, a photosensitive substance, which is synthesized by vitamin A and a protein. If vitamin A is destroyed after exposure and is not supplemented, rhodopsin will decrease, and as a result, people's vision will decrease in weak light, leading to blurred vision and even night blindness. Therefore, in order to prevent the decrease of rhodopsin, it is not appropriate to turn on fluorescent lamps and other lighting lamps when TV, but it is appropriate to use a weak red light to supplement the rhodopsin in the eyes. In addition, fluorescent lamps are also a kind of interference source, and the electromagnetic waves generated by them have a certain interference effect on TV, and sometimes even cause a slow rolling horizontal interference light band on the TV screen, which may also lead to a "buzzing" sound on TV. In addition, the bright fluorescent lamp will reduce the contrast between the TV image and the indoor light, and make the TV picture appear blurred. Watching TV in this environment will definitely make your eyes tired. Especially for the elderly, watching TV for a long time will make them feel blurred and even dizzy. Watching TV with fluorescent lamps on often can not only protect your eyesight, but also lead to impaired eyesight. The correct way is to replace the fluorescent lamp with a red light with weak light, or an incandescent lamp with small wattage, with soft light. Watching TV in this light is good for protecting your eyesight. From/news/20115210400.htm from/
