Our eyes have special receptors for blue light that, when stimulated, signal the brain to inhibit melatonin production, which is important for falling and staying asleep. Unfortunately, any lightbulb or screen that is yellow or white has a large blue component, so most people are exposed to a lot of blue light at night. 

As a result, wearing glasses that block 99% of blue light can make you tired sooner, allow you to fall asleep more easily, and improve sleep quality.
