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, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
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 ...
