Most blue light glasses filter 10–20% of blue light and use a nearly clear lens. PRVMAL DARK uses deep red lenses that block 99%+ across the full 400–500nm spectrum — the range proven to suppress melatonin. Every pair ships with an independent spectrophotometry report so you can verify the claim yourself.

1–2 hours before you want to fall asleep. That's the critical window when blue light from your phone, TV, and overhead lights does the most damage to your melatonin production. Consistency is key — wearing them at the same time every night gives your circadian rhythm the strongest signal.

The research on blue light and melatonin suppression is well-documented in peer-reviewed journals. Light between 400–500nm signals your brain that it's daytime. Block it, and your body produces melatonin on its natural schedule — meaning you fall asleep faster and sleep deeper. We cite our sources on our Science page.

The lenses are deep red. Everything looks warm red through them. Most people adjust within 5 minutes and stop noticing. The frames are a classic rounded shape in matte black — they look like normal glasses, just with red lenses.

Your PRVMAL DARK glasses. That's it. No filler, no fluff, no tiny booklet you'll never read. Just the thing that actually helps you sleep.

PRVMAL DARK currently ships with non-prescription lenses. They fit comfortably over most small-frame prescription glasses. We're exploring prescription lens options for a future release.

PRVMAL DARK is designed for indoor evening use — specifically the 1–2 hours before sleep. While the lenses do provide UV400 protection, the deep red tint significantly alters color perception, which makes them impractical for driving or outdoor activities.

Use a microfiber cloth with a gentle circular motion. For deeper cleaning, rinse under lukewarm water with a drop of dish soap, then pat dry with the cloth. Avoid paper towels, tissues, or clothing — these can scratch the lens coating.
