I bought this mask because I was having trouble with relaxing my eyes at night.  I would go to bed and could not relax my eyes enough to keep them closed.  I bought this mask and it not only helps me with that issue but it makes me fall asleep more quickly because I don't have any light to keep me awake.  I put the mask on and BOOM I am out.

It's great for sleeping in strange places, also for when my husband wants to stay up and I want to go to bed.  I honestly never thought light was such a sleep distraction but it definitely is.  I sleep soo much better now that I use this mask.

My only gripe is it doesn't stay on very well.  I wake up every single night with it off and have to put it back on depending on what time it is.  I am a side sleeper, but I don't toss and turn that much that it should come off.
