UT researcher earns international attention for discovering how blue light speeds blindness

The University of Toledo was recently featured in news outlets across the world for interesting research conducted by a faculty member in the College of Natural Sciences and Mathematics.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, discovered that blue light from smartphones and other digital devices can lead to age-related macular degeneration, a leading cause of blindness in the United States.

 The UT research was published recently in the journal Scientific Reports.

“This is a new trend of looking at our devices,” Karunarathne told Popular
Science. “It will take some time to see if and how much damage these devices can cause over time. When this new generation gets older, the question is, by that time, is the damage done?”

UT chemists discover how blue light speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. 

The process outlined in the study, which was recently published in the journal Scientific Reports, leads to age-related macular degeneration, a leading cause of blindness in the United States. 

“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.”  Read more
