According to a new study, blue light from smartphones, tablets and other similar backlighting gadgets can accelerate the blindness process.

Researchers at the University of Toledo claim that spending a lot of time staring at screens, especially in close proximity, will damage the eyesight and produce toxic chemicals in the eye light sensitive cells.

Blue light can make you blind

The study, published last month in Scientific Reports involved the exposure of living cells to different types of light. The researchers discovered that exposure to blue light results in “reactions that generate toxic chemical molecules in photoreceptor cells,” which are the cells in the retina that respond to light.

“If you look at the amount of light coming out of your cell phone, it’s not good but it seems tolerable,” according to John Payton, one of the researchers and a guest assistant professor at the University of Toledo’s Department of Chemistry and Biochemistry. “Some mobile phone companies add blue light filters on the screens, and I think it’s a good idea.”

Blue light filters on phones

In fact, both Apple and Android offer blue-eyed filters that change during night time, reducing the amount of blue light to avoid serious eye loads. A number of third-party applications that perform the same feature are also available for both desktops and smartphones.

For protection against blue light, Ajith Karunarathne, deputy professor of the aforementioned department and one of the researchers in the study, suggests wearing sunglasses that can filter both ultraviolet and blue light outside and avoid looking at smart phones at night.

“Each year, more than two million new cases of age-related macular degeneration in the United States are reported,” according to Karunarathne. “By learning more about the blind mechanisms in search of a method of intercepting toxic reactions caused by the combination of retinal and blue light, we hope to find a way to protect the vision of children growing up in a high-tech world.” Macular Degeneration

Macular Degeneration

Macular degeneration remains the leading cause of vision loss and eventually leads to total blindness. There is a vitamin E molecule called alpha tocopherol that attempts to ward off such cell death, but it does not have the same impact force as people age or if their immune system is compromised. Meanwhile, make sure you follow Karunathen’s advice and try to wear special glasses that can prevent the blue light from brushing your retina.
