The blue light from digital devices like smartphones could accelerate blindness, researchers found...

According to a research by the University of Toledo in the U.S., exposure to blue light almost every time might cause poisonous molecules to be generated in the eye's light-sensitive cells and lead to macular degeneration.

Researchers said as one of the leading causes of blindness in the U.S., macular degeneration does not lead to total blindness, but can make activities so difficult to perform.

“It's not a secret that blue light harms vision by damaging the eye's retina.

“Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop,"... said Dr Ajith Karunarathne, an assistant professor in the university's department of chemistry and biochemistry.

Macular degeneration is caused by the death of photoreceptors, a kind of light-sensitive cells.

Photoreceptor cells needs molecules called retinal to sense light and trigger signalling to the brain, enabling us to see.

“If you shine blue light on retinal, the retinal kills photoreceptor cells as the signalling molecule on the membrane dissolves,” said Kasun Ratnayake, a PhD student at the University of Toledo who was involved in the study.

“Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good,”
Ratnayake added.

To protect eyes from blue light, researchers advise people to wear sunglasses which filter both UV and blue light outside and avoid using smartphones or tablets in the dark.

By saying blue lights, we mean actual blue light? As in, color blue?

I believe our smart phones emit different colors of light, green, white, yellow, black, etc. why is blue singled out? Please I need to know.
