Our blue light glasses block up to 99% of high-energy blue light (wavelengths between 400–495 nm) and green light (approximately 495–520 nm), mainly emitted by artificial lights. Exposure to these wavelengths in the evening heavily suppresses melatonin production, the hormone that signals your body it’s time to sleep. By blocking this light, the glasses help maintain your circadian rhythm, allowing your body to recognize natural sleep cues, fall asleep more easily, and enjoy a deeper, restorative sleep.
