To help you find the best pair of blue light glasses, we consulted three optometrists to learn more about what to look for.

"Blue light blocking glasses filter out a range of blue light wavelengths and can reduce light sensitivity and glare from digital devices to help alleviate eye strain," explains Jennifer Tsai, O.D ...

Blue light glasses work by reflecting the light waves coming in so they bounce off the surface. There's a coating or filter on the lens that reflects the wavelength, or "blue" spectrum of light ...

One common factor is an abundance of blue light, the shortest wavelength in the visual spectrum. Constant exposure to blue lightwaves is not especially healthy but difficult to avoid.
