Blue light from your smartphones and laptops can damages vision and can speed up blindness, according to a new study. This research result was published on July 5 in Scientific Reports.
Long periods of time exposed to blue light, the kind phones, tablets and televisions give off, can damage vision and generate poisonous molecules in the eye’s light-sensitive cells, Researchers from the University of Toledo said.
Though the amount of light coming out of your cell phone seems tolerable this could accelerate macular degeneration and other eye diseases. It was also found that exposure to blue light triggers “reactions that generate poisonous chemical molecules in photoreceptor cells.
Eye disease such as macular degeneration is caused by the deterioration of light-sensitive cells in the retina. This disease is age-related and can cause blindness.
People should wear sunglasses that can filter both UV and blue light outside and avoid browsing on smartphones, laptops and similar gadgets in the dark, Researchers and an assistant professor at the University of Toledo said.
Nowadays, Some cell phone companies are adding blue-light filters to the screens, and I think that is a good idea. But for those devices which don’t have filters, the user can protect your eyes by wearing glasses with amber or orange-coloured lenses that can block out blue light.
