Claims that blue-light glasses help improve sleep and protect against damage to the retina were not supported. Researchers said the study included 619 people from six countries.
Blue light glasses may not be effective (at least not based on current research) but are usually safe. Therefore, experts say wearing blue light glasses daily is generally safe.

A study sponsored by the lens industry has shown blue light-filtering lenses decrease specific aspects of light emissions. Theoretical reductions in phototoxicity were 10.6% to 23.6%. [12] Additionally, melatonin suppression was reduced by 5.8% to 15.0% and scotopic sensitivity by 2.4% to 9.6%. Over 70% of the participants in this testing were ...
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.
Blue light has also been blamed for eye strain and discomfort. As a result, people have been shelling out for blue light-filtering spectacles in hopes of snoozing in peace and reducing visual fatigue.
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 ...
