📜 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).

Acetate at the front, where craftsmanship shows. Titanium at the temples, where engineering matters. A migraine glass that solves an old contradiction.

Prologue

For decades, you had to choose.
Now you don't.

Choice One

All-Acetate Frames

Strength: Italian luxury feel, depth of finish, plant-based richness.

Limitation: Heavier on the temples. Acetate temples can crack under stress over years.

Choice Two

All-Metal Frames

Strength: Featherlight, durable, structural integrity.

Limitation: Cold-feeling, less personality, can pinch the bridge during extended wear.

The Mosaic Golden Glass Solution

Acetate where you want warmth.
Titanium where you need precision.

A hand-finished cellulose acetate front carries the visual warmth and depth that defines the look. Beta titanium temples deliver featherlight comfort, structural durability, and zero pressure points. Two materials, each chosen for what it does best.

The Architecture

Two halves.
One whole.

The Front · Anterior

Cellulose
Acetate.

100%

Plant-Based

60+

Polish Steps

Hand-cut from solid blocks of cellulose acetate. Tumbled, smoothed, and polished across 60+ steps to achieve depth of colour and finish that injection-moulded plastics cannot replicate.

Hypoallergenic. BPA-free. Carries the visual warmth Italian eyewear has been famous for over a century.

The Temples · Lateral

Beta
Titanium.

45%

Lighter than Steel

2×

Stronger Tensile

Beta titanium is the same alloy used in surgical implants and aerospace components. Memory-flex behaviour means temples adapt to your face shape over time, then return to original form.

Hypoallergenic. Corrosion-proof. Engineered for hours of pressure-free wear without bridge fatigue or temple bite.

Frame Construction

Cellulose Acetate Front with Titanium Temples.

Hand-finished in our Surat workshop. The cellulose acetate front is precision-cut to match the lens curvature, then hand-polished. The beta titanium temples are precision-laser-cut, formed for ergonomic head curvature, and finished with a soft-touch matte coating.

The result is a frame that looks like luxury, weighs like nothing, and survives years of daily wear.

Section i.

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

Decades of clinical neuro-ophthalmic 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 Mosaic Golden Glass uses MR-8 optical resin from Mitsui — selected for its high Abbe value and zero chromatic distortion. Edges stay sharp. Colours stay true. The world simply looks softer.

Section ii. · Tint Selection

Two tints.
Same precision.

Light Tint

For mild migraine.

Office hours · indoor screens · everyday photophobia · gentle outdoor wear

58%

Tint Density

50%

VLT

A subtle rose tint with near-natural colour perception. Wearable in any setting without drawing attention to itself. The everyday migraine glass.

Dark Tint

For severe migraine.

Chronic photophobia · post-concussion · harsh outdoor · clinical-grade sensitivity

78%

Tint Density

40%

VLT

Deeper rose-amber. Maximum filtration. Built for chronic light sensitivity, severe migraine sufferers, and harsh outdoor environments where light becomes the enemy.

Section iii.

Five layers,
in sequence.

A premium migraine lens isn't one thing. It's a stack of engineered surfaces, each with a specific function, applied in a deliberate order, contributing to a single outcome: visual comfort.

Hard Coat

The scratch-resistant base. Survives years of daily handling, the in-and-out of cases, accidental brushes against bags and pockets.

Anti-Reflective

Eliminates ghost reflections from screens and overhead lights, the secondary glare that quietly compounds migraine triggers throughout the day.

iii

FL-41 Filtration Core The Heart

The functional layer. Tuned to neutralise the 480 to 520 nm migraine trigger band while preserving soothing green wavelengths the visual cortex calms toward.

Hydrophobic

Water beads off rather than smearing. Rain, sweat, splashes, condensation — none of it ends in a panicked wipe before walking into a meeting.

Oleophobic Finish

Repels oils and fingerprints. The final layer. Cleans up with a single pass of the included optical-grade microfiber cloth.

Section iv. · Evidence

Built on what the
science actually says.

Section v. · The Process

Tested.
Measured.
Documented.

Every batch of Sleepaxa Mosaic Golden Glass undergoes spectrometer-validated wavelength testing across the 480 to 520 nm migraine-trigger band, before it leaves our facility.

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

Section vi. · Real Days

What changes,
after a week.

No.

Comfort that disappears

The titanium temples flex naturally with your head. The acetate front sits warmly without pressure. The 3pm urge to take them off simply doesn't arrive.

No.

Migraine triggers soften

Fluorescent flicker, harsh LEDs, supermarket lighting, oncoming headlights — the everyday triggers that used to start an attack often feel measurably gentler within 7 to 14 days of consistent wear.

No.

Photophobia eases

Bright environments stop feeling like an assault. Indoor lighting becomes manageable. Outdoor light becomes navigable. Daily life becomes a little quieter.

No.

Eye fatigue dissolves

Long screen hours stop ending in burning eyes and tension headaches. Contrast sharpens. Glare dims. Focus stays where you put it.

No.

Light sensitivity, all day

Wear them indoors at work. Wear them outdoors in the sun. Same FL-41 filtration carrying through every environment. Acetate warmth meeting titanium precision, hour after hour.
