Blue Light Glasses for Better Sleep and Eye Health
Some people believe blue light can cause eyestrain and poor sleep and look to blue light glasses as a way to counteract these issues. Blue light is one of the colors on the visible light spectrum and is found in natural daylight. However, it’s also used as part of the backlighting for computer screens, smart devices and TVs. If you spend your work and recreation time looking at screens, you may want to try these glasses to take care of your eyes. You can also find glasses cleaners and glasses repair kits too.
Do Blue Light Glasses Work?
Blue light glasses have benefits, including:
Preventing eyestrain
Reducing the risk of eye disease
Improving sleep
Protecting eyes from dryness
If you watch TV or scroll through your phone late at night, blue light glasses may help improve your sleep. Exposure to blue light can interfere with your production of melatonin, a hormone that helps make you sleepy. Blocking the blue light from your screens can improve melatonin levels, which helps you fall asleep more quickly and provides better quality sleep.
When it comes to preventing computer-related eye strain, no scientific evidence supports the use of blue light glasses. In fact, little evidence indicates blue light causes digital eye strain. The problems experienced by computer users are generally caused by focusing on one screen for a long time, dry eyes and not taking enough breaks.
However, some scientists have found blue light makes you blink less often. This contributes to dry eyes. Eye drops are an excellent way to combat dry, itchy eyes, but blue light glasses may help prevent them in the first place.
Do Blue Light Glasses Help With Headaches?
People who experience frequent headaches are often looking for ways to prevent them. Blue light glasses may be able to help, depending on the cause of the headaches. It’s unlikely glasses that block blue light will have any effect if your headaches are a result of eyestrain.
People with light sensitivity may have better luck with blue light glasses. If blue light is causing issues, headache symptoms may improve when you wear blue light glasses. As wearing these glasses doesn’t cause any harm, it may be worth a try. You can also use pain medications to help manage headaches.
Where to Buy Blue Light Glasses
CVS stocks a wide range of blue light glasses, so you can find something that suits your needs. If you wear prescription glasses and want them to have blue light-blocking capability, talk to your optometrist.
