The research carried out by researchers at the University of Toledo suggests that lonv exposure to the kind of blue light our gadgets produced could generate “poisenous molecules” to the eyes light sensitive cells thereby damaging it. Their findings were published on July 5 in Scientific Reports.
The experiment was carried out by exposing living cells to various types of lights, and blue light was the one that triggered a reaction that generated a poisenous chemical. The group was aiming to understand how cells respond to everyday blue light exposure from devices like phones and TVs, according to a release.
Dr payton in a statement released said that “If you look at the amount of light coming out of your cell phone, it’s not great but it seems tolerable, Some cell phone companies are adding blue-light filters to the screens, and I think that is a good idea.”
When too much blue light is focused on the retina, the light sensitive part of the eye, it detoriates the cells in the eye and causes diseases such as macular degeneration. The disease is said to be age-related and when in excess it can cause blindness.
Currently, 11 million people in the US have some sort of macular degeneration, according to a report published on Brightfocus Foundation, a nonprofit organization that supports research.
The patient number will likely double by 2050. Dr. Ajith Karunarathne, A researcher and an assistant professor at the University of Toledo,told the Guardian that 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( but funny enough, night time is when the use of such gadget is most fun).
