Blue-light toxicity

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.[1][2] Increasingly, blue blocking filters are being designed into glasses to avoid blue lights purported negative effects. However, there is no good evidence that filtering blue light with spectacles has any effect on eye health, eye strain, sleep quality or vision quality.[3]

Blue LEDs are often the target of blue-light research due to the increasing prevalence of LED displays and Solid-state lighting (...
