Relax
The Relax Collection is made for the hours when your day starts winding down. Warm-tinted lenses help reduce exposure to harsh, cool light from evening screens, indoor lighting, and other common sources of artificial light.
Choose from two specialized lenses designed for comfortable evening wear, whether you're relaxing with a show, working after dark, or settling into your nighttime routine.
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.

INTERNATIONAL STANDARDS
Every claim substantiated by lab measurements to ISO 12312-1, ANSI Z80.3, and AS/NZS 1067.
LAB-CERTIFIED, NOT SELF-DECLARED
Every lens is independently tested by Micor-Light Optics against international optical standards. The spec sheet for each lens is one click away on its product page — for the curious, the cautious, and the practitioners.
