And the death of light sensitive cells is irreversible, and its death can directly lead to the loss of vision or even complete.
Second, cause visual fatigue. Because the wavelength of blue light is short, the focus point is not in the center of the retina, but in the position of the first one points from the retina. At this point, to see the outside image, the eyeball will be in a tense state. If this situation persists, it may lead to the deepening of myopia, the appearance of Diplopia, the easy serial of reading and the inability to concentrate. affect our efficiency.
Third, affecting the rhythm of People's division. Blue light suppresses melatonin secretion, and melatonin is an important hormone affecting sleep, which is known to promote sleep and regulate time lag. So blue light can cause people's sleep is not high or insomnia and other symptoms.
