Blue light, from digital devices and the sun, transforms vital molecules in the retina into cell killers, Science Daily reports.
Optical chemistry research at The University of Toledo shows how that process leads to macular degeneration, a leading cause of blindness in the United States.
The study was recently published in the journal Scientific Reports.
"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. "It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop."
Macular degeneration is caused by the death of photoreceptor cells in the retina.
