Working at night, despite my old shutters closed, day passes a little through. So I bought this mask to be totally in the dark. I'm not very satisfied ... The mask is hard and unwieldy, it is not very strong, I would have preferred a resilient overall. Then I thought having the nose would be ideal, and not at all !!! Becuase, clarity password at this shape for the nose, and is not reflected at all in the dark! In the end I spend my sleep mask to keep me for the better and thus be properly clad in the dark. The hull of the eyes I do not like finally! In short, after not even a less use, it ended on my shelf gathering dust, I no longer use it, it irritates me more than it soothes me to sleep lol
