📜  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).

Voilav

Lighter than
a thought.

A migraine glass engineered around a single principle: if you can feel it, we haven't done our job.

01 — The Premise

Most migraine glasses
are built for shelves.
We built ours for hours.

Heavy frames. Pressure points. The afternoon urge to take them off and rub the bridge of your nose.

For someone with chronic migraine or photophobia, this isn't a small annoyance. It's the reason most people stop wearing therapeutic eyewear within a week of buying it.

02 — The Material

Ultem.
Originally for aircraft.

217°C

Heat Tolerance

9×

Stronger than Acetate

0%

BPA · Allergens · Toxins

A high-performance thermoplastic engineered for aerospace cabins, surgical instruments, and structural components in extreme environments.

In the Voilav , it becomes something quieter: a frame that disappears.

Frame Construction

Ultem Aerospace-Grade Polymer.

Hand-finished in our Surat workshop. Hypoallergenic. BPA-free. Engineered for 12+ hour wear without bridge fatigue, temple bite, or pressure-point irritation. The kind of build that stops being noticeable within minutes of putting them on.

03 — The Lens

FL-41 isn't a tint.
It's a calculation.

Decades of clinical research have isolated a specific narrow band of light, between 480 and 520 nanometers, as the primary trigger for migraine pain and photophobic discomfort.

FL-41 is a precision-tuned rose-amber filter that selectively neutralises this exact range, while preserving the soothing green wavelengths the visual cortex finds most calming.

The Voilav uses MR-8 optical resin, selected for its high Abbe value and zero chromatic distortion. Edges stay sharp. Colours stay true. The world simply looks softer.

04 — Tint Intensity

Two tints.
One technology.

Same FL-41 filtration core. Same indoor-outdoor versatility. Different intensities for different lives.

Light Tint

For mild migraine.

Everyday photophobia · screen-heavy days · indoor triggers

58%

Tint Density

50%

VLT

Subtle rose tint. Near-natural colour perception. Wearable in every lighting condition without drawing attention.

Dark Tint

For severe migraine.

Chronic photophobia · post-concussion · harsh outdoor light

78%

Tint Density

40%

VLT

Deeper rose-amber. Maximum filtration. Built for clinical-grade light sensitivity and chronic migraine sufferers.

05 — Lens Architecture

Five layers.
Every lens.

01

Hard Coat

Scratch-resistant base. Survives years of daily handling, accidental brushes, and case in-and-out.

02

Anti-Reflective

Eliminates ghost reflections from screens and overhead lighting, the kind of glare that quietly triggers attacks.

03

FL-41 Filtration Core The Heart

The functional layer. Tuned to neutralise the 480-520 nm migraine trigger band while preserving soothing green wavelengths.

04

Hydrophobic

Water beads off instead of smearing. Rain, sweat, splashes — no streaks, no panic-cleaning before a meeting.

05

Oleophobic Finish

Repels oils and fingerprints. Single-wipe clean with the included microfiber cloth.

06 — Evidence

Built on what the science
actually says.

07 — The Process

Tested.
Measured.
Documented.

Every batch of Sleepaxa Voilav undergoes spectrometer-validated wavelength testing across the 480 to 520 nm migraine-trigger band.

No estimates. No assumptions. Just measured filtration performance, validated against the same standards used in clinical photophobia research.

08 — Real Days

What changes
after a week.

→

Comfort that disappears

No nose pressure. No temple bite. The 3pm urge to take them off simply doesn't arrive.

→

Triggers soften

Fluorescent flicker, harsh LEDs, mall lighting — the everyday triggers feel measurably gentler.

→

Photophobia eases

Bright environments stop feeling like an assault. Indoor and outdoor become navigable again.

→

Eye fatigue dissolves

Eight hours on a laptop. Three hours on a phone. The light doesn't stop, but the strain does.

Prescription Available

From 1.56 to 1.74.
Your prescription, perfected.

From standard 1.56 for low to moderate prescriptions, all the way to ultra-thin 1.74 for high powers. The Voilav adapts without compromise.
