Smartphone blue light exposure may speed up blindness

Hindustan Times, India: The blue light transmitted by smartphones and digital devices can accelerate blindness by transforming vital molecules in the eye’s retina into cell killers, a study has found. Blue lightemitted from smartphones and other digital devices can accelerate blindness by transforming vital molecules in the eye’s retina into cell killers, a study has found. Macular degeneration, an incurable eye disease that results in significant vision loss starting on average in a person’s 50s or 60s, is the death of photoreceptor cells in the retina. Those cells need molecules called retinal to sense light and trigger a cascade of signalling to the brain.
