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.
Peak spectral sensitivities are in the blue region of the visible spectrum (near 440 nm). People with this condition generally show nystagmus ("jiggling eyes"), photophobia (light sensitivity), reduced visual acuity, and myopia (nearsightedness). [30] Visual acuity usually falls to the 20/50 to 20/400 range.
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 ...
EnChroma are a brand of color corrective lenses designed to address the symptoms of red–green color blindness.Studies have shown that these lenses can alter the appearance of colors, but they do not restore normal color vision, [1] and generally agree that they do not allow the wearer to see "new" colors.

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.
