2. Biological effects of high-energy visible light - Wikipedia

   en.wikipedia.org/wiki/Biological_effects_of_high...

   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.

   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 ...

7. Anti-reflective coating - Wikipedia

   en.wikipedia.org/wiki/Anti-reflective_coating

   An antireflective, antiglare or anti-reflection ( AR) coating is a type of optical coating applied to the surface of lenses, other optical elements, and photovoltaic cells to reduce reflection. In typical imaging systems, this improves the efficiency since less light is lost due to reflection.
