Sleepaxa Opulent Carbon Grey FL-41 Migraine Glasses – Relief for Migraine, Photophobia & Light Sensitivity
Blocks 100% of blue and green light to 550nm, so your body starts making melatonin on time.
Third-party spectrophotometer readings for this exact lens. Every batch is verified before it ships.
Two Indian patents

Everything left of the line is stopped.
Most blue-light lenses shave a little off the blue band. This one holds a hard cutoff at 550nm, which is where the research on melatonin suppression actually sits. Every batch is checked on a spectrophotometer before it ships.
Will this fit me?The three numbers inside your arm
Turn over the arm of the glasses you wear now. Three numbers are printed inside, something like 52-18-140. That is lens width, bridge, and arm length in millimetres.
This frame is 55-14-145 and 140mm across the front. If your current pair slides down your nose, you want a narrower bridge. If it presses on the sides of your nose, you want a wider one.
| Lens width | 55mm |
| Bridge | 14mm |
| Arm length | 145mm |
| Front width | 140mm |
| Lens height | 49mm |
| Size | Medium |
Amber or Red?Two tints, two jobs
Sleepaxa Amber
The all-day pair. Indoor and outdoor, day or evening, screen comfort with colour balance kept. No time limit.
Sleepaxa Red
For severe sleep trouble. Indoor only, 30 to 60 minutes before bed. Maximum melatonin, deepest sleep prep.
If you can only take one pair, take Amber. Most customers add Red later.

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 Opulent Carbon Grey 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.
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 Opulent Carbon Grey 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.
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.
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 vi. · Real Days
What changes,
after a week.
No.
01
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.
02
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.
03
Photophobia eases
Bright environments stop feeling like an assault. Indoor lighting becomes manageable. Outdoor light becomes navigable. Daily life becomes a little quieter.
No.
04
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.
05
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.
The Unboxing
Designed to be
remembered.
An unboxing isn't a formality. It's the first conversation between us and you. Every layer, intentional.
3D-Printed Outer Box
Tied with a satin ribbon. Tamper-proof construction. Less like packaging, more like a gift, even when you're buying it for yourself.
Velvet-Finished Case
Soft-touch velvet exterior over a structured hard shell. Magnetically secure. The kind of case that earns its place on your desk.
Premium Microfiber Cloth
Optical-grade. Lint-free. Sized to clean both lenses in a single motion. The kind that just works.
Premium Travel Pouch
Lightweight, drawstring-finished, slim enough for any bag pocket. For days when the case stays home but your glasses come along.
"The first thirty seconds of opening a Sleepaxa box should already feel like the product is working."

The hybrid
that ended
the compromise.
