Solutions for Blue Light Harm 

As you can guess the best solution not to expose yourself to blue light is to live in a cave and to get only full spectrum sunlight, but we all know this is impossible.

Try to avoid light at night and if you just can’t avoid all light and need to do some work on your PC use Iris or other blue blocking software.

Iris has Sleep type preset which removes almost all blue light from your screen.

In front of the TV use some blue blocking glasses or just sunglasses. Sunglasses are sometimes even more effective that blue blockers since they also block UV light.

And lastly, remove all LED light bulbs in your home. Although energy efficient they are bad for your sleep. Use the good old incandescent light bulbs or if you can use candles sometimes.
