This Review Title is Weird smell, but great for dry eyes. and the content is: I have to sleep with a sleep mask on every night because I sleep with my eyes open and they get dried out. These have a little puffy lip on the inside that sits right on top of your eyelid, and therefore keep your eyes closed.  So I would highly recommend these to anyone who sleeps with their eyes open!  They do have a really weird, chemical smell to them.  They're supposed to have a 'calming' smell, but honestly it is just sickening.  I leave them out of the package for about a week before I actually sleep with them to let them air out; it helps tremendously. Once you get rid of the smell, they're great.  Also, the elastic does stretch after a while, but it does that on any sleep mask and it's usually time to replace it at that point anyway..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
