Calm Lavender Blue Light Glasses
Calm lavender lenses are the gentlest tint we make for sensitive eyes. They filter 59% of blue light while keeping two-thirds of the visible light coming through, so a room still looks like a room. Reach for them around seven in the evening, when full-strength sleep lenses would be too much but plain glasses aren't enough.
The lab data
- Blue light blocked: 59% across 400–500nm
- Visible light transmission: 66%
- Filter category: 1
- Wear it: early evening wind-down, or any time bright indoor light feels like too much

One catalog. Every kind of light.
Every lens lab-certified, every spec public. Pick the lens for the light you're in.
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.
