Darkness isn't just comfort.
It's biological signal.
When we set out to design the Lunar, we kept returning to a single finding from sleep medicine: melatonin suppression by light is dose-dependent, instantaneous, and profound. A single photon landing on your retina at 11pm can delay melatonin onset by up to 90 minutes. Not metaphorically — measurably, in blood.
Most sleep masks address this casually. A layer of fabric, a thin strip of foam. We treated it as an engineering problem. Total light occlusion. Zero gap at the nose bridge. Contoured cups that create a sealed environment without touching the eye surface.
The weighting came second. 280 grams of micro glass beads distributed across the orbital ridge — enough to activate the same calming pressure receptors as a weighted blanket, without the heat retention that disrupts core body temperature.
The silk is 22 momme mulberry — the highest grade used in luxury bedding. Hypoallergenic, temperature-neutral, and gentle enough for nightly use for decades. We didn't compromise on it. We couldn't — your face spends a third of its life against it.
