When you’re a light sleeper, literally anything can keep you awake. Ambient light is a common problem, particularly if you share a room or work shifts. The Manta Sleep Mask & Blackout Stickers help you get some rest by putting your eyes in total darkness. It works in bright daylight, and even heavy sleepers should feel the benefits. You can grab this sleeping aid now for just $29.99 via the PopSci Shop.

Sleep masks are not new, of course—but most are both uncomfortable and ineffective at blocking ambient light. Manta solves both of these problems with a unique design.

On the inside of this mask, you will find two eyepieces. These are designed to enclose your eyes rather than merely cover them. As a result, no light can creep in from the side. Each eyepiece also has extensive memory foam cushioning around the edge, and you can easily adjust the spacing.

Manta is perfect for light sleepers, night shift workers and travelers. The mask will help you get some much-needed REM sleep, and you can use the supplied stickers to cover annoying notification lights.
