How blue light accelerates blindness

The results showed that exposure to blue light triggers retinal reactions that produce toxic chemical molecules in photoreceptor cells.

Are you addicted to your smartphones, laptops, and tablets? According to a study by a professor of Indian descent, the blue light emitted by these digital devices can affect the retina of the eye and lead to age-related macular degeneration.

 

Macular degeneration, an incurable eye disease that results in a significant loss of vision, on average between 50 and 60 people, is the death of photoreceptor cells in the retina. These cells need molecules called retinas to detect light and trigger a cascade of signals to the brain.

 

The results showed that exposure to blue light triggers retinal reactions that produce toxic chemical molecules in photoreceptor cells. “We are constantly exposed to blue light, and the cornea and lens of the eye cannot block or reflect,” said Ajith Karunarathne, assistant professor at the University of Toledo in Ohio, USA.

 

It is no secret that the blue light damages our vision by damaging the retina of the eye, “he added, adding that the non-retinal photoreceptors produced in the eye are useless, requiring a continuous supply of retinal molecules.

 

Poisonous If the blue light shines on the retina, retinal photoreceptor cells kill when the membrane signaling molecule is dissolved, “said Kasun Ratnayake, a graduate student at the university.” Photoreceptor cells do not regenerate in the eye. “When they die, they die forever.”

 

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

 

The toxicity produced by the retina by blue light is universal. Can kill any cell, “Karunarathne said,” To protect your eyes from the blue light, wear glasses that can filter out ultraviolet rays and blue light, and avoid looking at their cell phones or tablets in the dark, “he suggested in front.
