The Effects Of Blue Screens On Our Health

How do you like to unwind at the end of the day? Maybe you watch a favorite television show, scroll through social media feeds, or play games on an electronic device. In this 24/7, always-on world, chances are you check your text messages or e-mail one last time before closing your eyes for the night, or fall asleep to the sounds of late-night television hosts.

Get to know the health effects of blue screens and the light they emit now.

Eyestrain And Damage


Looking at screens all day can cause eyestrain and damage. Just like any other muscle, eye muscles get worn out from overuse. We also blink less when we are looking at screens, up to half as much as our usual blink rate, which leads to dry, irritated eyes. Researchers are increasingly understanding the special risks blue light poses for our eyes. A study conducted at the University of Toledo found blue light can damage the retina. As we get older, the damaging effects of blue light become greater. Our eyes’ natural defenses against blue light begin to decrease, putting us at greater risk of developing age-related macular degeneration, a leading cause of blindness in older adults.
