The Mindfold Sleep and Relaxation Eye Mask is a unique sleep mask made to block light completely. The Mask comes with eye cavities so your eye lashes don't rub against the mask, and it does not smudge eye make-up!
It's capable of 100% light blockage, the foam is soft and the stretchable headband's velcro doesn't connect at the back.
There is a lot of eye room depth, so your eyelashes don't touch it.
The Velcro strap joins on the side, instead of the back, so you don't feel a lump at the back of your head. If you sleep with the back of your head on a pillow, it's very comfortable and you won't even notice the strap.
If you are looking for a mask that totally blocks out light, and lets you open your eyes without your lashes touching it, then this is the mask you want. The Tempur-Pedic Sleep Mask is another good solution, according to other sources, but it costs three times as much. If you're a side sleeper, get the Dream Essentials Escape Sleep Mask.
