How It Works
Complete darkness is a prerequisite for melatonin production and quality sleep architecture. Even small amounts of light through eyelids suppress melatonin. The Manta mask achieves darkness without the discomfort that causes most people to abandon sleep masks within a week.
Modular Eye Cups
Individual cushioned cups sit around each eye, not on them. Allows blinking and REM eye movement without pressure.
Total Blackout
Adjustable cups seal around the nose bridge and temples. Blocks 100% of light including edge leakage.
Adjustable Strap
Velcro strap sits above the ears, not on the back of the head. Compatible with side sleeping and CPAP.
