Blue Light is Making Us Blind, Say Researchers
by Heather Callaghan, Editor
Our addiction to screens isn’t just hurting our social lives or nature – it’s making us physically blind.
Molecules that we need to be able to see, called retinal, turn into cell killers when they interact with blue light, researchers have just discovered.
University of Toledo researchers made a shocking discovery that the “blue light” emanating from our smartphones and other screens is literally doing permanent damage to our vision.
A dark room at the University of Toledo is where researchers have found blue light, specifically, leads to macular degeneration.
“Macular Degeneration is one of the leading causes of blindness in the United States and all around the world,” said assistant professor in the UT Department of Chemistry and Biochemistry, Ajith Karunarathne.
According to this new research, blue light can makes us blind.
The researchers said molecules that we need to be able to see, called retinal, turn into cell killers when they interact with blue light.
“We don’t really at this point know what is the major cause. We know how it happened because there are multiple paths that lead to the cell death,” said Karunarathne.
The researchers want to get to the bottom of that and develop some sort of eye drop to reduce damage. In the meantime, they suggest avoiding looking at your phone in the dark.
Scientists knew that blue light could damage retinas – they just didn’t know how or why.
They suggest not using smartphones and other screens in the dark.

Other Eye Saving Techniques
- I use the Screen Shader app on my laptop and it has made all the difference! No more piercing eye strain while I read and work all day and into the evening. This Chrome extension shades away the blue light in order to match natural daylight. You can customize it, too.
- You could limit screen use to daytime only.
- There are also yellow glasses that people wear in the evenings to counteract the effects of blue light.
- Eat wild blueberries – people report better vision and they regrow neurons!
- Don’t forget to take many breaks throughout your workday – your boss will thank you.
