Harmony Rose FL-41 Migraine Glasses
Harmony is our rose FL-41 lens, tuned to the narrow band of light most often linked to migraine and photophobia. Blocking peaks at 47.74% at 510nm, right in the middle of that band, while the lens stays light enough at 67.56% transmission to wear through a normal working day under office lighting.
The lab data
- Peak blocking: 47.74% at 510nm
- Mean blocking across the 480–520nm FL-41 band: 44.55%
- Visible light transmission: 67.56%
- Filter category: 1
- Wear it: whenever bright or fluorescent light is a trigger, at any hour
Passes ISO 12312-1, ANSI Z80.3 and AS/NZS 1067 — internationally compliant in all three. Cleared for daytime driving; not for night driving (transmission is below the 75% threshold). Lab-certified by Micro-Light Optics, 24 December 2025. UV400 rated.
Sleep ZM glasses are not a medical device and are not a treatment for migraine. If headaches are frequent or severe, please see a doctor.

WHAT MAKES SLEEP ZM DIFFERENT
14 lens types. Not strength variants. Distinct lenses.
Other brands count "14 lenses" by stocking 3 strengths of the same color. We don't. Every Sleep ZM lens has a different spectral profile, a different use case, and a different lab certification.
