In today's time, the smartphone is as useless as it is for us. The smartphone has become a major part of our lives, so our way of sleep has changed too. It is not surprising that after examining the notification by lying on the bed, our eyes are damaged.
Researchers at the University of Toledo say that the blue light emanating from the smartphone screen can cause blindness. Research has found that blue light gives birth to poisonous reactions in the retina of the eye, which understands the light and gives the signal to the brain. Consequently, poisonous chemicals reactions kill the photoreceptors in the eyes, which can not be corrected once again after being spoiled.
