SleepZM's Crystal frame pairs with a 100% Red lens (SleepAidMax), one of 14 purpose-built lenses in our Healthy Light Living system. Lab-certified by Micor-Light Optics, this lens blocks 100% of blue and green light across 380-580nm — SleepZM’s strongest lens for the last hour before bed, making it a fit for SleepZM’s strongest pre-sleep lens. Every lens is precision-tinted polycarbonate with 100% UV400 protection, plus anti-smudge, scratch-resistant coating and integrated anti-radiation film (22.17% visible light transmission, Cat 2 per ISO 12312-1) — built to hold up to daily wear. The TR-90 frame is lightweight enough for all-day use, for women and men. Every pair ships with anti-fog cloth, case. Light sensitivity is personal, so we recommend a 2–3 week trial to find the lens that fits your routine. SleepZM's catalog spans more than 50 frame-and-lens combinations across the 14-lens system — explore the full lineup to match a lens to every room, screen, and time of day.
