Why Consider Blue Light?


  • There has been a 70% Increase in the average size of a smartphone screen between January 2007 and May 2014.
  • Mobile devices are now responsible for 40% of YouTube traffic.
  • 34% of all adults use digital devices for between 4 and 6 hours a day–mostly smartphones and tablets.
  • 14% spend as much as 10-12 hours per day using them

All digital devices have one point in common: they give off blue light, which harms our eyes. How?

Blue light is fifteen times more harmful to the retina than other colours in the spectrum. The effects of Blue Light can have a serious impact on sleeping patterns. Sustained exposure can damage cells in the retina and can cause stress, pain and tiredness.
