NeuroCalm FLX+ | The World's First Dual-Band FL-41 Migraine Lens
Patented Dual-Band Technology · Patent 587746
Every migraine glass on the market is FL-41.
Ours begins where FL-41 ends.
For 30 years, FL-41 has been the gold standard for migraine and light-sensitivity glasses. We build the best FL-41 lenses you can buy — and then we engineered the lens that goes beyond it. NeuroCalm FLX+ is the world’s first dual-band FL-41 lens, developed in our own research lab and protected by a granted patent.

The problem with a single tint
Ordinary FL-41 dampens one broad band of light (roughly 480–520nm). It helps — but migraine photophobia isn’t driven by a single band, and blocking too much light dulls color and dims your world. A blunt instrument for a precise problem.
The science: two bands blocked, one protected
NeuroCalm FLX+ targets the wavelengths tied to migraine pain — and deliberately preserves the ones shown to calm it. That’s the difference between a tint and true spectral engineering.
| Wavelength band | What it does | NeuroCalm FLX+ |
|---|---|---|
| 460–490nm | Melanopsin / ipRGC pain pathway | Attenuated |
| 520–560nm | Green light linked to reduced migraine pain | Preserved |
| 585–600nm | Cone-driven pain pathway | Attenuated |
Every other migraine glass blocks one band and hopes. Ours targets two and protects a third.
FL-41 vs NeuroCalm FLX+
| Ordinary FL-41 | NeuroCalm FLX+ | |
|---|---|---|
| Bands filtered | One broad band (480–520nm) | Two precision bands |
| Green light | Dimmed with everything else | Deliberately preserved |
| Approach | A tint | Engineered spectral filter |
| Protection | Off-the-shelf | Granted Patent 587746 |
Who it’s for
Chronic migraine and photophobia. Fluorescent office lighting and screens. Bright, high-glare days. If light is a trigger, NeuroCalm FLX+ is built for you — indoors and out.
Your lenses, your way
Available in zero power, single-vision prescription, progressive, bifocal and prism, with high-index 1.67 / 1.74 options and premium anti-reflective, anti-scratch, UV400 coatings. Most brands sell one option. We build the full range.
Engineered by researchers, not marketers
NeuroCalm FLX+ was developed at Acieon Labs, our research division, and is protected by granted Patent 587746 (dual-band selective light attenuation, all 10 claims allowed). Lead inventor: Suraj Dubey, senior optometrist. Clinical advisor: Dr. Monica Chaudhry — 37+ years in optometry, former faculty at AIIMS New Delhi. Our research is published openly with citable DOIs.
Frequently asked
Is NeuroCalm FLX+ just FL-41 with a different name?
No. FL-41 filters a single broad band. NeuroCalm FLX+ is a patented dual-band lens that attenuates two separate pain-linked bands while preserving migraine-calming green light.
Can I get it in my prescription?
Yes — single-vision, progressive, bifocal and prism, plus high-index options.
Can I wear it outdoors?
Yes. NeuroCalm FLX+ is designed for indoor and outdoor light.
Is it clinically proven to cure migraines?
No lens cures migraine. NeuroCalm FLX+ is engineered to help manage light sensitivity and reduce light-triggered discomfort, based on published photobiology research.
