Why it works

These glasses block out light-wavelets which humans usually experience as blue-colored. Blue light is especially prominent during sunrise and triggers our body to wake up and become more alert (1).

Wearing blue-light blocking glasses will let you produce the necessary melatonin when you sleep even if you look at a TV or computer screen before bed.
