How Blue Light Affects Our Eye Health

 

In large amounts, high-energy light from the sun -- like ultraviolet rays and blue light -- can boost your risk of eye disease. That’s raised concerns about whether blue light from digital screens is harmful. More research is needed. 


Experts think digital eyestrain, or computer vision syndrome, affects about 50% of computer users. Symptoms include dry, irritated eyes and blurred vision. 


Blue light may also damage your retinas. That’s called phototoxicity. The amount of damage depends on wavelength and exposure time. Animal studies show even short exposure (a few minutes to several hours) may be harmful. A filter that cuts 94% of blue light has been shown to lessen damage.
