Perfect Sleep Mask for Side Sleepers: The Umisleep sleep mask is designed to fit snugly around your temples, with a unique height difference design that reduces pressure on the temples when side sleeping. This helps you sleep better and relax more.

What are the Functions of the 3D Eye Mask?: The 3D contour cup is connected, making the mask more breathable. It puts no pressure on your eyeballs or nose, and the deeper eye sockets ensure your lashes won't rub.

Cut off Light Perfectly: The invisible nose bridge is designed to block light from the nose area, creating a completely dark sleep environment. This lets you sleep well anywhere, anytime.
