Blue light glasses are becoming increasingly common among consumers, which makes sense—the amount of time people spend staring at screens every day is constantly going up, thanks in large part to the proliferation of mobile devices like smart phones and tablets.
Blue light is everywhere, including in the sun’s rays, but when eye doctors talk about blue light, we’re most commonly talking about the light emitted by those electronic devices and fluorescent fixtures. While blue light is harmless in itself in small amounts, excessive exposure can be damaging to the eyes. Many eye doctors recommend glasses with blue light filters as a way to mitigate that possible damage, especially for people who can’t help but stare at screens for hours a day as part of their work.
Here are just a few of the benefits associated with using blue light glasses while working or otherwise spending time on computers or other electronic devices:
- Better, more consistent sleep: Spending time on your screen before bedtime can mess with your body’s ability to fall asleep, as blue light exposure makes you more alert and delays the release of melatonin. This is why so many doctors caution against using screens right before bed. Try turning off devices an hour or two before bedtime, and if that’s not possible, use blue light filtering glasses while using them.
- Fewer headaches: A lot of screen time (and blue light exposure) can lead to headaches. Blocking out the blue light with these filtering glasses can help you avoid those symptoms.
- Less eye strain: Another common problem people with a lot of screen time experience is being overburdened with eye strain. Looking at a screen all day is hard on the eyes, and can result in feelings of stress as well as eye and muscle strain. Blue light glasses that block out those rays can help you reduce the amount of eye strain you experience.
- Better overall eye health: It’s not just short-term issues with eye strain and headaches that can be alleviated by using blue light glasses. You can also protect yourself against potentially contracting various eye diseases over the long term. The cornea and eye lens do have some natural filtration ability, but they are unable to block blue light, and that could result in damage to your retina over time, as well as possible macular degeneration, which could lead to lost eyesight.
- You can continue using your devices: While there might be other reasons for you to try to limit your use of your devices, blue light filters mean you’ll no longer have to count blue light exposure as one of those reasons. You can continue using your devices when you want and as much as you want without having to experience eye strain as a consequence of doing so.
