The color is not possible to achieve through normal vision, because the lack of incident light (in the black) prevents saturation of the blue/yellow chromatic signal (the blue appearance). Self-luminous colors These mimic the effect of glowing material, even when viewed on a medium such as paper, which can only reflect and not emit its own light.
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.
Studies have been conducted on blue light filtering eyeglasses, [5] [27] which uses special blue light blocking lenses for eye protection against blue light. [ 27 ] [ 28 ] All visible light wavelengths can be transmitted through the spectacle lens, [ 28 ] but some portions of the blue-violet light spectrum are selectively attenuated by coating ...
Blue-light-blocking glasses claim to reduce eye strain from devices, but scientists say there are better ways to reduce the strain on eyes.
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.

Color matches made in the paint industry are often aimed at achieving a spectral color match rather than just a tristimulus (metameric) color match under a given spectrum of light. A spectral color match attempts to give two colors the same spectral reflectance characteristic, making them a good metameric match with a low degree of metamerism ...
Zee has been shopping and wearing blue light glasses without prescription lenses since November 2018, and has worn blue light-blocking lenses consistently on weekdays beginning in July 2020 in the ...
