Blue light is toxic molecules evolve in the light-sensitive cells of your eye, especially in your photoreceptor cells, when you spend a long time with your smartphone, laptop or tablet.
"We are constantly exposed to blue light, and the cornea of the eye The lens can not block or reflect it," Dr. Ajith Karunarathne, assistant professor at the Department of Chemistry and Biochemistry, in a press release.
Karunarathne suggests wearing sunglasses that can filter out UV and blue light outdoors, suggesting that you look at your devices in the light and not in the dark.
"It's poisonous.When you shine blue light on the retina, the retina kills photoreceptor cells as a signaling molecule on the membrane lves," said Kasun Ratnayake, a graduate student. "Photoreceptor cells do not regenerate in the eye and when dead they are dead forever."
