How cool are these bad boys?
Our optical grade red lenses block 100% of blue and green light from 400nm to 550nm. This is the exact range that has been shown in clinical trials to lower melatonin and negatively impact our sleep.
They can improve mental health, sleep, focus and facial muscle pains. 
These are for evening use when blue light protection with clear vision as it gets darker is also needed.
