If you’re like me (and most of my patients), you are probably spending increasingly more time in front of a screen. While we can certainly get a lot done with these devices, the effects of these screens can be harmful to our eyes, especially when we are looking at them non-stop. I’ve been using blue light glasses for the past couple years and have noticed an improvement in avoiding eye strain. Here are some reasons I wear blue light blocking glasses, and why you might consider using them yourself.
What is Blue Light?
To put it simply, the colors you see on your screen, and all around you are a combination of the color spectrum. The blue waves are the shortest and therefore output the most energy. Blue light can be both beneficial and harmful.
The blue light on your screen is human-made and much more potent than the natural blue light you get outside. The blue light emitted from your computer, tablet, and smartphone is significant. Given the amount of time we spend on our screens, this type of light can cause harmful side effects.
Wearing glasses that block the blue light can be beneficial to your health.
Better Sleep
Because blue light has such a high energy level, it also energizes the brain. The blue light causes a delay in the release of melatonin, which helps get you to sleep.
The best way to counteract this is to stop using your devices one to two hours before bed; however, blue light blocking glasses will allow you to use your device right before bedtime.
Reduces Age-Related Macular Degeneration (ARM)
ARM is one of the leading causes of blindness. Using blue light blocking glasses can help prevent or delay the condition.
Studies have shown that blue light can damage light sensitive cells in the retina causing blindness.
Helps with Eye Strain
When you look at your device for an extended time, your eyes start to feel tired. Glasses that filter blue light can help you focus and reduce the strain on your eyes. As a result, your eyes don’t feel as tired.
Make sure that you are taking regular breaks from your screen as well as reducing your screen time. Using glasses that filter blue light can help reduce the harmful effects of using your devices all day long.
