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.
Several standards for sunglasses (see below) allow a general classification of the UV protection (but not the blue light protection), and manufacturers often indicate simply that the sunglasses meet the requirements of a specific standard rather than publish the exact figures. The only "visible" quality test for sunglasses is their fit.
The blue light spectrum is an essential part of the visible spectrum with wavelengths of about 400-480 nm. [1] Blue light is primarily generated by Light-Emitting Diodes (LED) lighting and digital screens, it has now become prevalent in the world around us. [2] LED lighting creates white light by combining blue light with other wavelengths ...
