Relief
When ordinary blue light glasses aren't enough, the Relief Collection offers specialized lens tints designed for more challenging light environments.
Choose from three precision-tinted options developed for different types of light sensitivity, including screens, fluorescent lighting, and environments that can feel especially harsh on sensitive eyes. The collection includes specialized FL-41 and FL-60 tints for those looking for targeted visual comfort.
THE COMPLETE 14-LENS SYSTEM
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.

DISTINCT LENS TYPES
Each engineered for a different kind of light — not the same lens in 3 strengths.
