Sleep Glasses — Amber & Red
India's only clinically backed, patent-based eyewear brand
Two in three have
eye strain. One in four
can't sleep. Both?
Burning eyes by 9pm. In bed by 11, still awake at 1. Seven hours of sleep that feels like four. Two separate complaints, one shared cause — the light you spent all evening staring into. And the data says you are very much not alone.

Sound familiar?
If any two of these are
your evening —
🌙
Tired, but wide awake
You're exhausted by 10. In bed by 11. Still staring at the ceiling at 1am, brain running.
🔥
Eyes burning by 9pm
Dry, heavy, stinging. You keep rubbing them. The screen starts to feel physically uncomfortable.
😶🌫️
Groggy every morning
Seven hours in bed, feels like four. You need two coffees before you're a person.
📱
One more scroll
You know you should stop. The phone doesn't feel tiring — that's exactly the problem.
Most people fix this by trying harder — earlier bedtime, no caffeine, a new pillow. None of it touches the actual trigger.
Here's why
Your eye has a sensor
that only reads one thing:
is it daytime?
It doesn't care what you're watching.
It only cares what colour the light is.
A separate set of cells in your retina — nothing to do with vision — tells your brain whether it's day or night. They're tuned to a narrow band of light, peaking around 480 nm. Screens and LEDs are full of it. So at 11pm your eyes say "goodnight" and those cells say "it's noon" — and melatonin doesn't show up.
Remove that band of light, and the signal stops. That's the whole idea. Everything below is just proving we actually do it.
The measurement
So — does the lens
actually remove it?
Every brand says yes. Almost none will show you a reading. We sent both lenses to an independent lab, had the transmittance measured wavelength by wavelength against three international standards, and published the whole thing — including the parts that make us look worse.

Why Sleepaxa
Most eyewear is sourced.
Ours is engineered.
Almost every "blue-light" or sleep lens sold in India is pulled from a generic manufacturing catalogue with a tint applied afterwards. No patent. No clinical board. No lab report — which is why you have never been shown one. Sleepaxa is India's only clinically backed, patent-based eyewear brand: engineered from the wavelength up by Acieon Labs, reviewed by a clinical advisory board, and published openly for anyone to tear apart.

Red · Circadian560 — 14.92% VLT · Cat 3
380–550 nm — the band that matters
Read it left to right. In the shaded zone both curves sit on the floor — that's light being removed, not dimmed. Amber lifts off around 530 nm and is back to 96% by 600 nm, which is why you can still see colour and wear it outdoors. Red stays at literal zero all the way to 550 nm and only starts climbing at 570 nm. At 560 nm: Amber passes 66.61%, Red passes 0.29%. That gap is the entire difference between the two products.

Good to know
Fair questions.
Amber or Red — which one should I buy?
Amber if this is your first pair, or the problem is eye fatigue, severe eye strain and mild-to-moderate sleep trouble. At 50.47% VLT you can wear it indoors and outdoors, all evening. Red if sleep is the priority above everything else — it removes blue, green and part of yellow entirely (0.00% through 550 nm), worn for the hour before bed, indoors. Most people start with Amber. People who take sleep seriously end up with Red.
Why is the lens tinted? Can't it be clear?
No — and that's the whole point. Removing a wavelength removes its colour. A lens that looks clear has not removed much. The tint is the evidence. Amber measures 0.13% mean transmittance across 380–500 nm; Red measures 0.00%. A near-clear "blue-cut" lens attenuates a narrow slice near 415–455 nm and leaves the rest intact.
Can I drive in these?
No. Amber is not intended for night driving — high-VLT lenses are advised after dark. Red is Filter Category 3 and marked not suitable for driving at all; evening and indoor use only. Both reports state this openly, which is more than most brands will tell you.
Can I get my prescription in these?
Yes. Both Amber and Red come in zero power, single-vision prescription and progressive, with high-index options for thinner lenses. You can also send in your own frames for a custom lens fit.
What does "100%" actually mean here?
It means the measured mean transmittance across 380–500 nm on the Red lens reads 0.00% on the independent test record — not a rounded marketing figure. Amber reads 0.13% (99.87% removed) and 0.05% at 480 nm. Every figure on this page is traceable to the two lab reports above. Batch-to-batch variation is normal and expected.
How long before I notice something?
Eye comfort is usually noticeable the same evening. Sleep changes depend on consistency — wear it in the same window every night rather than occasionally. There's a 30-day money-back window either way.
Are Sleepaxa glasses a medical device?
No. Sleepaxa eyewear is assistive visual-comfort eyewear designed to support light management. It is not a medical device and not a substitute for medical diagnosis or treatment — please consult a qualified professional for clinical concerns. Patent filings describe intellectual property protection, not medical-device approval.

The evidence
The patents and research behind these lenses are developed and documented by Acieon Labs, Sleepaxa's research & IP division: nine DOI-linked open-access works on Zenodo, one granted Indian patent (No. 587746), and five pending applications.

All spectral figures shown are measured values reproduced from independent test records held on file (Amber: ISO 12312-1:2022, ANSI Z80.3-2018(R2023), AS/NZS 1067.1:2016+A1:2021 · Red: ISO 12312-1:2013(A1:2015), ANSI Z80.3-2018, AS/NZS 1067.1:2016). Batch-to-batch slight variation is acceptable. Comparison figures for generic "blue-cut" lenses describe typical market products and are indicative only. Reviews shown are real, verified customer experiences shared with Sleepaxa; a curated selection, not a live feed, and individual experiences vary.
