Blue light from cell phones, computer screens, and overhead lighting can block production of up to 99% of the sleep hormone melatonin, causing chronic disruption of the circadian rhythm. Our amber glasses are specially designed to block over 99% of the blue wavelengths that cause insomnia, while letting through plenty of amber light to allow you to remain productive throughout your evening. Studies suggest that wearing amber glasses for 45 minutes each night can result in up to an hour more sleep per night! Amber glasses have proven particularly effective for Chronic Insomnia, ADHD insomnia, Bipolar insomnia, Delayed Sleep Phase Syndrome (DSPS), and Shift Work Sleep Disorder. Free case included!
