I have started wearing a sleep mask on trips as I find it fairly hard getting to sleep in odd places. It works for getting to sleep but almost 100% of the time the mask will no longer be covering my eyes when I wake up. The straps are tight but to no avail.
Occasionally it's still on my head but most of the time it will be in some random place on my lap or nearby. I don't know how it gets off, I assume I take it off unconciously because of the feeling of something weird on my face, but I really have no idea. The result is that I am woken up by the light rather than my alarm.
Has anyone found a way of preventing this issue and keeping the mask on?
