"Blue light glasses filter out blue light," says Dr. Craig See, MD, an ophthalmologist at Cleveland Clinic Cole Eye Institute. "They allow the other colors of light to pass through and reach the eye."
Do blue light glasses work to protect your eyes from screens? Ophthalmologists share whether there are benefits to blue light glasses and tips to protect eyes.
Blue-light-blocking glasses are said to help reduce eye strain and headaches — are they for you?
Glasses with a notch filter (e.g. EnChroma glasses) filter a narrow band of light around 590 nm that excites both the L- and M-cones (yellow-green wavelengths). [12] They are often combined with an additional stopband in the short wavelength (blue) region to minimize the tint on the lenses and approximate a neutral-density filter. They improve ...
Blue light is absorbed by the structural proteins, enzymes, and protein metabolites found in the lens. [9] The absorption of blue light creates yellow pigments in the lens's protein. The lens progressively darkens and turns yellow. [9] Blue light is absorbed by the lens, preventing blue light from reaching the retina at the back of the eye. [12]
Blue-light-blocking glasses claim to reduce eye strain from devices, but scientists say there are better ways to reduce the strain on eyes.
