In a study of studies, researchers concluded that eyeglasses that block blue light might not deliver on claims made by advertisers or optometrist offices. They caution consumers to think twice about shelling out the extra cash for the specs.

“The amount of blue light our eyes receive from artificial sources, such as computer screens, is about a thousandth of what we get from natural daylight," he said. "It’s also worth bearing in mind that blue-light filtering lenses typically filter out about 10-25% of blue light, depending on the specific product. Filtering out higher levels of blue light would require the lenses to have an obvious amber tint, which would have a substantial effect on color perception.”

I just use a screen filter on my desktop and phone about 2hrs before sleep and it makes a tremendous difference. I don't know of the alleged benefits outside of sleep, but I do know it clearly helps with that.

Do you regularly spend time outside during the day? I read that doing that will basically negate any need for managing screens like this.
