The Problem

Migraine Isn't Just a Headache.
It's a Life Disruptor.

Millions suffer in silence — unable to work, travel, or enjoy daily life. Light sensitivity makes it worse. Generic glasses don't help.

The Science

Why FL-41 Lens Tint Works

Not all light is equal. Specific wavelengths between 480–520nm are known to activate pain pathways in migraine-prone brains.

1

Targeted Wavelength Filtering

FL-41 tint selectively filters the 480–520nm wavelengths most associated with triggering discomfort.

2

Clinically Referenced Approach

FL-41 lenses have been referenced in peer-reviewed research for supporting comfort during photophobic episodes.

3

Everyday Wearability

Unlike dark sunglasses that can worsen photophobia, FL-41's rose tint allows comfortable use indoors, outdoors, and at screens.

Not a Medicine — A Comfort Tool

Sleepaxa FL-41 glasses are designed for day-to-day comfort. Not a medical device or substitute for clinical treatment.

Peer-Reviewed Evidence

Backed by 30+ Years of
Published Research

FL-41 lens science is not new. It's been studied in leading peer-reviewed journals for over three decades.

1991 · Foundational Study

Cephalalgia — Tinted Spectacles in Childhood Migraine
The original FL-41 study demonstrating significant reduction in migraine frequency with tinted lenses.

Foundational research identifying the neural pathways through which light triggers migraine pain.
2009 · Ophthalmology

Demonstrated FL-41's benefit in reducing photophobia and improving comfort in light-sensitive patients.
2016 · Brain Journal

2024 · Recent Research

American Journal of Ophthalmology — FL-41 neural pathway activation
Latest 2024 research confirming clinical benefit of FL-41 tinted lenses for photophobia management.
2023 · Cochrane Review
Singh S, et al.
Cochrane Database — Blue-light filtering lenses
Found generic blue-light coatings (400-450nm) have insufficient evidence — FL-41 targets the actual pain wavelengths (480-520nm).
The Sleepaxa Difference: Generic blue-light coatings target 400-450nm. The melanopsin-ipRGC system that drives migraine photophobia peaks at 480-520nm — a 30-80nm spectral mismatch. NeuroCalm FLX+™ is precision-engineered to filter the actual trigger wavelengths.
