[Other] Blue Light From Smartphone, Computer Displays Can Accelerate Blindness: Study

Hi Mi Fans,

Are you addicted to your smartphones, laptops and tablets? The blue light emitting from these digital devices can affect your eye's retina and lead to age-related macular degeneration, according to a recent study.

Macular degeneration, an incurable eye disease that results in significant vision loss starting on average in a person in their 50s or 60s, is the death of photoreceptor cells in the retina. Those cells need molecules called retinal to sense light and trigger a cascade of signalling to the brain.

The findings showed that blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in photoreceptor cells.
We are being exposed to blue light continuously, and the eye's cornea and lens cannot block or reflect it," said Ajith Karunarathne, Assistant Professor, University of Toledo in Ohio, US.

"It's no secret that blue light harms our vision by damaging the eye's retina," he added. Since photoreceptors, produced in the eye, are useless without retinal, one needs a continuous supply of retinal molecules to see.

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signalling molecule on the membrane dissolves," explained Kasun Ratnayake, doctoral student researcher at the varsity. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."


In the study, published in the journal Scientific Reports, when the team introduced blue light to other cell types in the body, such as cancer cells, heart cells and neurons, they died as a result of the combination with retinal. Blue light alone or retinal without blue light had no effect on cells.

"The retinal-generated toxicity by blue light is universal. It can kill any cell type," Karunarathne said. To protect your eyes from the blue light, wear sunglasses that can filter both UV and blue light outside and avoid looking at your cell phones or tablets in the dark, he suggested.
