You may still be able to see things on the periphery.

The result is that you lose the ability to see the center of your field of vision.

It happens when a structure in the back of your eye, the macula, becomes damaged as you get older. Blue light and macular degenerationĪge-related macular degeneration (AMD) is the number one cause of sight loss in people over 50 years old, according to the American Academy of Ophthalmology (AAO). Here’s a quick look at the risks and benefits of blue light waves. While current research indicates that blue light from computer screens and handheld devices probably does not pose a serious risk to your eyes, there are some other risks to consider. Risks and side effects of blue light exposure Researchers point out that because LED devices are relatively new, there aren’t any long-term studies to measure what blue light may do to your eyes over the course of your lifetime. However, it’s difficult to say whether blue light, red light, or infrared light caused this damage because the face mask included all three. One recent exception: Doctors reported that a woman who used an LED face mask to improve her skin had distorted vision and a retinal lesion afterward. While some animal studies have shown that blue light can damage cells in the retina, eye doctors say there is little proof that blue light damages the retina of the human eye. So far, research does not appear to validate the concern about blue light eye damage. Another 15.5 percent used the devices 12 to 14 hours per day - a sizable increase in screen time, probably due to changes in the way people work during the pandemic. This is because people spend so much time using them at such a close range.Ī 2020 study published in the Indian Journal of Ophthalmology found that during COVID-19 lockdowns, for example, 32.4 percent of the study population used a blue-light-emitting device 9 to 11 hours per day. Nevertheless, some eye health experts have expressed concern about exposure to blue light from backlit digital screens and devices. And you’re exposed to a lot of it - the natural blue light from the sun far exceeds the amount from any one device. Those structures don’t keep out blue light. Your cornea and lens protect the light-sensitive retina at the back of your eye from damaging UV rays, for example.

Your eye is equipped with structures that protect it from some kinds of light.
