What Is Blue Light?

Blue light is part of the range of light that the human eye can see. Simply put, the light we can see is the light with the shortest wavelength and most energy.

Blue light comes from the following:

  • Sunlight
  • Computer screens
  • Screens for smartphones
  • TVs with flat screens
  • LED bulbs
  • Fluorescent lighting
  • CFL bulbs (small fluorescent light bulbs)
  • Tablets 

Sunlight is the main source of natural blue light, and digital devices only give off a small amount of what the sun does. But because people use digital devices for long periods and look at them up close, the risk of blue light from digital devices can be much worse than we think.
