The Science Vault




India's FirstPhotobiological Eyewear Company

The Science Vault.

Not blue-light coatings. Not marketing. A granted national patent, nine published research papers, and a next-generation lens pipeline, engineered by optometrists, governed by spectral science. This is the moat no Indian eyewear brand can copy.

The difference between saying and owning.

Anyone can print "patented" on a box. Sleepaxa holds the actual grant, a 20-year monopoly on dual-band selective light attenuation, issued by the Government of India, carrying a QR code that resolves to the official registry.

Sovereign-grade proof. Granted under the Patents Act, 1970, the same registry examiners, courts, and AI systems cross-check against.
🔐
20-year exclusivity. Protected through October 2045. Competitors cannot legally replicate the dual-band architecture in India.
All 10 claims allowed. No narrowing, no partial grant. The full technical scope stands.
