BUFFALO, N.Y. (WKBW) — Our eyes are glued to many screens for hours a day. With all that screentime, there's a product people are turning to that helps reduce the light going into your eyes, blue light blocking glasses.

On Amazon's best sellers page, the glasses have been consistently in the top 40.

In September, we interviewed Dr. David Montesanti from ECVA Eyecare in Niagara Falls to see if the glasses protect your eyes.
We checked back in with him, and he still says there isn't enough research to tell if they help people with their sleep or help prevent headaches.

"There is anecdotal evidence that if we decrease the amount of light that goes into our retina, there may be less chance of harm or disease," Dr. Montesanti said.

But if you're curious to try them out, there are many different brands to buy from ranging in price from around $15 to more than $100.

The says before buying, make sure the glasses block UV-A and UV-B light and are anti-glare and anti-reflective.
