Exposure to blue light can speed up blindness, new optical chemistry research at The University of Toledo claimed to show.

Blue light found in digital device displays and from the sun causes molecules in the retina to change so that they kill cells, according to UT News, which reported on the research. When enough cells are killed, macular degeneration results.

Macular degeneration is a leading cause of blindness in the U.S. with more than two million new cases reported each year, UT News pointed out.

“We are being exposed to blue light continuously, and the eye’s cornea and lens cannot block or reflect it,” University of Toledo department of chemistry and biochemistry assistant professor Dr. Ajith Karunarathne said to UT News. “It’s no secret that blue light harms our vision by damaging the eye’s retina.” Karunaranthe said that research could help slow down the process and lead to new therapies like eye drops that prevent the killer compounds from being made.

“Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good,” study researcher Kasun Ratanayake said to PC Gamer.

The poisonous reaction did not occur if only blue light or retinal molecules were present, UT News reported.

Karunaranthe recommends wearing sunglasses that filter blue light along with UV rays and to avoid staring at electronic screens in the dark, UT News reported.

PC Gamer also recommends installing f.lux, a program that mimics natural light, on your PC. iOS’s Night Shift mode comes directly from f.lux and filters out blue light as well.
