“Blue light has a dark side.” “Use our glasses to block adverse blue light effects from screens.” 

If you’ve seen headlines and ads like these, you’ve probably wondered — is blue light from screens bad for your eyesight?

(Known as AMD, this disease, which affects the central part of the retina, is the leading cause of vision loss in North America.)

Dr. Panos G. Christakis, a specialist with the Retina Service at UHN’s Toronto Western Hospital, and Dr. Shamrose Khan, an assistant clinical professor with the School of Optometry and Vision Science at the University of Waterloo (Ont.), were kind enough to help provide answers for Good Times magazine’s latestReader’s Question column: Does Blue Light Up AMD Risk?
