Frequently Asked Questions

Benefits

Red is the best color for blocking the light that inhibits sleep. That's because it's not just blue light that interferes with our circadian rhythm, as the term 'blue-blockers' would suggest – it's also green light. Specifically, it's light in the melanotic action spectrum of 400-570nm. For more information check out our Technology page for more details on how Carbonshade can help you!

A healthy sleep cycle is vital to the immune system.Blue light suppresses melatonin in the brain and keeps the body awake. Carbonshade blocks 99.8% of all harmful blue light. This allows your sleep cycle or circadian rhythm to adjust and can positively impact sleep-related grogginess or headaches, and dieting. Please see our Technology page for more details on how Carbonshade protects you from blue light.

Carbonshade glasses are not a direct cure for headaches, however if your headaches are sleep related or LED light related, then you may benefit from this product. Shop Carbonshades.
