What is blue-violet light?

High Energy Visible Light (HEV; 390-500nm) is part of the visible segment of the light spectrum. Scientific evidence has indicated there are benefits to HEV exposure, however potential associated risks have also been mentioned. (Dualism of blue light).

Blue-violet light

  • It is considered to be the potentially harmful part of the HEV spectrum and it is the range between 390 – 440nm of the light spectrum.
  • It is everywhere, although its intensity varies greatly. While a typical LCD computer monitor produces a brightness of 250 cd/m2, a clear blue sky at midday is 32 times as bright. Direct sunlight can be thousands of times as bright.

Blue light filter solutions from ZEISS
