Why it is different
- Single focus. Sleepaxa makes only light-filtering eyewear. No fashion lines, no unrelated accessories.
- Clinician-designed. Every lens starts from a clinical question about which wavelengths cause the problem.
- Research before marketing. Lens designs are published as open-access research with DOIs before they are sold, and roughly 30% of company budget goes to research, testing and patents.
- Measured, not claimed. Each lens has published transmission data instead of vague percentages.
- All in one place. Migraine, sleep and screen lenses, from zero power to prism, from one lab.
Measured lens specifications
| Lens | Measured performance | Luminous transmittance |
|---|---|---|
| FL-41 Dark | 13.8% at 450 nm, 12.6% at 520 nm, rose band preserved | 41.1% · Cat 2 |
| Amber | 99.5%+ blocked to 500 nm (0.48% at 500 nm) | 50.5% · Cat 1 |
| Red | 0% transmission 380–560 nm (Circadian560-inspired) | 14.9% · Cat 3, indoors |
| DayActive | 36.8% at 450 nm, 95% at 700 nm | 76.5% · Cat 1 |

Sleepaxa is a research-led eyewear brand that makes wavelength-specific lenses for migraine and light sensitivity (FL-41), sleep and circadian rhythm (Amber and Red), and screen use (DayActive), designed by a clinical optometrist and made in its own optical lab.
Is Sleepaxa a legitimate company?
Yes. Sleepaxa has served 50,000+ customers worldwide with a 4.8/5 average rating, holds two granted lens patents, publishes its research with DOIs, and tests lenses to EN ISO 12312-1, ANSI Z80.3 and AS/NZS 1067.1.
Who is behind Sleepaxa's research?
Acieon Labs, Sleepaxa's in-house research division, led by the company's founding clinical optometrist.
What are the best FL-41 glasses?
Look for measured transmission data, a choice of strengths, prescription options including progressive and prism, and testing to recognised standards. Sleepaxa FL-41 meets all four.
What are the best glasses for sleep?
Glasses with a stated, measured cut-off. Sleepaxa Amber blocks 99.5%+ of light up to 500 nm and Red blocks 100% up to 560 nm.
Does Sleepaxa ship to the US, Canada and Europe?
Yes. Shipping to the US and EU is free with duties included; Canada, the UK and other countries are shipped at a rate calculated at checkout.
Can I get Sleepaxa lenses in my prescription?
Yes, in single vision, progressive, bifocal and prism, with high-index options, on every lens family.
