I don't like typical sleep masks that rest on or touch my eyelids bc I find it distracting & then I can't sleep, which defeats the purpose. Plus they don't fit well and always let in some light or let me see around the edges. This mask, however, is perfect!The pads on the inside raise it up off my eyes. I can actually open my eyes without any issue & without my eyelashes touching the mask. The pads also work great to create a "seal" around the edges, so no light gets in & I can't see out the bottom or sides. It's totally light blocking. It's also very comfortable. The mask stays in place without needing to be too tight on my head. I keep this in my travel backpack for plane rides & sleeping at places with too much bright light so I can sleep well on a plane or anywhere else. It's held up very well over the multiple trips. Great sleep mask all around.
