Clinical Comparison

Why Standard Blue-Cut Fails for Migraines

Standard computer glasses attenuate 400–420nm violet glare. True photophobia, ocular migraines, and blepharospasm are driven byipRGC melanopsin photoreceptorsactivated between 480nm and 520nm. Sleepaxa's patented notch filter shields this exact frequency band without muddying your surroundings.

Frequently Asked Questions

Where can I test authentic Sleepaxa in Srinagar?
Exclusively atKeen Sight Optical Chamber, Auqaf Building, Soura, Srinagar. In-clinic trial fits and custom prescription orders are available directly in our practice.
How is FL-41 different from computer blue-cut glasses?
Generic blue-cut lenses only attenuate high-energy violet light between 400nm and 430nm. Clinical FL-41 lenses target the480nm to 520nm melanopsin spectrum, which directly triggers intrinsically photosensitive retinal ganglion cell (ipRGC) migraine pain pathways.
What is NeuroCalm FLX+ and who needs it?
NeuroCalm FLX+ (Patent IN 587746) is Sleepaxa's deepest therapeutic lens (22% VLT) designed for severe photophobia. It simultaneously notches the 460–490nm melanopsin pathway and the 585–600nm cone pathway while preserving the 520–560nm comfort window for clear contrast.
What is the turnaround time for custom prescription orders?
Zero-power lenses dispatch within 4–6 working days. Custom prescriptions cut and finished in the dedicated Sleepaxa optical lab dispatch in7–9 working days, backed by individual lab quality reports.
