WASHINGTON (Circa) -- An increase in exposure to blue light can accelerate blindness, a new study from the University of Toledo shows.

Blue light causes poisonous molecules to develop in your eye's light sensitive cells, especially your photoreceptor cells, if you spend long periods of time using your smartphone, a laptop or a tablet.

"We are being exposed to blue light continuously, and the eye’s cornea and lens cannot block or reflect it,” Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said in a press release.

Karunarathne sugg ests wearing sunglasses that can filter out UV and blue light outdoors. It is also suggested that you look at your devices in the light and not in the dark.

“It’s toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves,” Kasun Ratnayake, a PhD student researcher said. “Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good.”
