Have you heard of blue light glasses? They aren’t really blue, but the makers of blue light glasses claim that the lenses block a large percentage of the blue light that’s emitted from screens. It’s a good idea. With more people spending hours in front of screens, there have been more reported incidences of troublesome eyes, according to optometrists in Pittsburgh, PA. But just because blue light glasses makers make these claims, does that mean they really work? And is blue light such a big deal that you should invest in blue light glasses?

What is Blue Light and Why is it a Concern?

You can’t see blue light, but it’s definitely there. In fact, if you’re reading this, you’re being exposed to blue light right now. Or rather, your eyes are, since your eyes absorb light. If they didn’t, you’d be blind as a bat, because light is the reason that we can see anything. Blue light is a high-energy, short-wavelength light emitted by digital screens, LED lighting, and even the sun. Excessive screen time—and the resulting exposure to blue light— can contribute to dry eyes, eye discomfort and even potential sleep disturbances.

Can Blue Light Glasses Reduce Eye Strain?

While blue light glasses may provide some relief, taking regular breaks and adjusting screen settings is also an effective way to reduce discomfort. Still, technology is so new that science really doesn’t have long-term data on this. After all, most of us can still remember years in our childhood where home computers didn’t even exist. End result? It’s too early to have a definitive answer to this question.

Do They Help With Sleep?

Exposure to blue light in the evening does suppress melatonin, making it harder to fall asleep. Avoiding blue light a few hours before sleep may be beneficial for those who struggle with sleep disruption due to screen use.
