It took me a week or two to adjust sleeping with the eye mask on. The eye rest blocks light very well. Whether the weight actually promotes relaxation is hard to tell. However, I've come to enjoy wearing it. 80% of the time the sleep mask stays on the entire night. When I move a lot, however, it sometimes slips off. After a year of usage, the straps became very loose. The eye mask now falls off easily. I'm disappointed since I'd like to continue using it.

When I move a lot during the night, the straps make wearing the mask uncomfortable. I'd think two straps would be better in distributing the weight/pressure, and making sure the mask stays on during sleep.
