According to a recent study, blue light emitted by smartphones, tablets, and other similar backlit devices can accelerate the process of blindness.
Researchers at the University of Toledo claim they spend long periods looking at screens, especially nearby, that will damage vision and produce toxic chemicals in the light-sensitive cells of the eye. This in turn, the researchers say, could accelerate macular degeneration and other eye diseases.
Blue Light May Blind You
The study, published last month in Scientific Reports involved exposing life cells to various types of light. The researchers discovered that exposure to blue light "causes reactions that produce 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 that comes from your cell phone, it's not great, but it seems bearable," said John Payton, a researcher and visiting professor at the Faculty of Chemistry and Biochemistry, University of Toledo. "Some cell phone companies are adding blue light filters to the screens, and I think that's a good idea."
Blue Light Filters on Phones
In fact, both Apple and Android offer blue light filters that turn on at night, reducing the amount of blue light to avoid heavy eye strain. A number of third-party applications that perform the same function are also available for desktops and smartphones.
For protection against blue light, Ajith Karunarathne, assistant professor in the above 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 smartphones at night ,
"Every year, more than two million new cases of age-related macular degeneration are reported in the US," said Karunarathne. "As we learn more about the mechanisms of blindness in finding a way to trap toxic reactions through the combination of retina and blue light, we hope to find a way to bring the vision of children into a high-tech world protect."
Macular degeneration remains the leading cause of vision loss and can eventually lead to total blindness. There is a vitamin E molecule called alpha tocopherol that tries to prevent such deaths, but it does not have the same fighting power as people age or when their immune system is compromised. In the meanwhile, you should follow Karunarathne's advice and try to wear special glasses that can prevent blue light from interfering with the retina.
