Washington: Are you addicted to your smartphones, laptops, and tablets? The blue light emitting from these digital devices can affect your eye’s retina and lead to age-related macular degeneration, according to a research led by a professor of Indian-origin. Macular degeneration, an incurable eye disease that results in significant vision loss starting on average in a person in his 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 signaling to the brain.
The findings showed that blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in photoreceptor cells. “We are being exposed to blue light continuously, and the eye’s cornea and lens cannot block or reflect it,” said Ajith Karunarathne, Assistant Professor, the University of Toledo in Ohio, US. “It’s no secret that blue light harms our vision by damaging the eye’s retina,” he added.
