📜  Sleepaxa Patent Portfolio
GRANTED
NeuroCalm FLX+™

Indian Patent IN 202521094370 | All 10 Claims Approved

Dual-band selective light attenuation technology. Simultaneously filters 460-490nm (melanopsin/ipRGC pain pathway) and 585-600nm (cone-driven pain pathway) while preserving the beneficial 520-560nm green band. Addresses both migraine pain mechanisms identified by Harvard research (Noseda et al., 2016). India's first granted patent in photobiological eyewear.

PENDING
Circadian560™

Indian Patent Application IN 202521120977

Peak-blocking circadian protection technology. Achieves 100% attenuation of blue light at the melanopsin activation peak, with comprehensive blocking extending to the 560nm upper boundary of the melanopsin sensitivity envelope. Engineered for maximum melatonin protection during evening screen use, based on the published action spectrum (Brainard et al., 2001, Journal of Neuroscience).

Master the Light: Precision Protection for Sensitive Eyes

Stop letting harsh environments dictate your comfort. The Sleepaxa® Clarte (Jet Black) is a high-performance optical tool engineered for those who experience neurological distress from light. While others see a stylish frame, you wear a sophisticated shield designed to neutralize the agonizing flicker and high-energy blue light of the modern world.

Why Clarte is the Engineered Standard:

  • Instant Neural Relief: Our lenses act as a high-precision barrier, filtering the specific 480nm-520nm wavelengths that trigger light-induced pain and photophobia.

  • 👓 High-Clarity CR-39 Engineering: Moving beyond standard plastic, Clarte features optical-grade CR-39 lenses. These provide glass-like transparency with zero distortion, allowing your visual cortex to relax.

  • 🧬 Neurocalm FLX+™ Technology: Featuring our advanced Neurocalm FLX+ filtration system, specifically tuned to dampen the overstimulation of the trigeminal nerve.

  • 🛡️ Dual-Action Blue Light Filtration: Beyond photophobia relief, Clarte is fortified with a Blue-Cut shield that filters harmful HEV light from digital screens, preventing retinal stress and digital eye strain.

  • Retro-Italian Craftsmanship: The frame is sculpted from premium, BPA-free Cellulose Acetate. It offers a lightweight, hypoallergenic experience that feels as good as it looks.

  • 🛡️ Total Surface Defense: Each lens is armored with an Advanced Neuro-Coating. This multi-layer shield eliminates back-glare and repels water and oils for a perpetually clear view.

  • 🦾 Industrial-Strength Tension: Featuring Elysian hard metal spring hinges, this model maintains a consistent, secure fit regardless of how active your day is.

Engineered for Your Environment:

  • Corporate Offices: Neutralizes the exhausting pulse of fluorescent and LED ceiling lights.

  • Digital Integration: Provides a soothing barrier against HEV blue light from high-resolution displays.

  • Retail Exposure: Filters the high-intensity glare typical of shopping malls and large public venues.

  • Low-Light Clarity: Enhances visual contrast in dim settings while still providing full protection.
