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’ve got lenses that supposedly block UV and blue light, and they’ve been great, because they somehow block the spectrum of light that triggers migraines in me. They’ve got a slight amber tint to them, and I’m ok seeing the world in slight sepia tones since it means only getting migraines once or twice a year instead of once or twice a month.
