100% Blue Light Blocking Glasses
I AM SLEEPING. SO. MUCH. BETTER. OLIVIA, YOU ARE AN ANGEL! - KATEY
My number one, non negotiable for quality sleep: 100% blue light blocking glasses.
These 100% Blue Light Blocking Glasses block 100% of blue light, and are designed for evening use.
They can help increase melatonin levels and lower cortisol, enabling you to fall asleep faster, wake up less through the night, sleep longer and wake more refreshed.
With light our primary zeitgeber (factor to control the circadian rhythm), there is NOTHING more important than this.
Note that you need these glasses even if you avoid screens before bed, as ceiling lights contain blue light too.

A 2018 clinical trial by Columbia University, blocking out blue light for 2 hours before bed improved symptoms of insomnia, such as difficulties falling asleep and waking unrefreshed, by 20%.
