Hi, I have a similar issue. From time to time I have the feeling that air came out of my eye, while I under the mask. When I rub my eyes, it feels like there is air or water behind. It makes a strange noise. Any explanation for that? brgs V. Sorry, I missed to log in. previous post was mine. brgs V.
