Our glasses are specifically designed to block blue light at night time, allowing you to wind down your day while your body starts naturally preparing for sleep.

Blue Block Glasses is based in Toronto, Ontario. We're highlighting the risks posed by artificial light before bed. We provide a novel solution to the problem - specially designed glasses that block light in the blue spectrum. Blue blocking glasses have been linked with natural increased melatonin levels and better sleep quality.
