Welcome @annienelson, I can definitely relate to your CPAP problems as they are the same ones I have dealt with on and off for the past couple of years. The air getting into the eyes is really annoying and probably bothers me the most also.

I also have a problem with sometimes overtightening the mask. I started using a cloth comfort cover on my full face mask and stopped worry so much about leakage as long as it wasn't too bad and affecting my AHI numbers. Finding the right mask that works best for your face and situation sometimes takes awhile. I've probably tried more than 7 or 8 different ones including one that covered my entire face and only lasted one night. A good sleep therapist/PA can help you if the mask is a problem.

I am currently using a Fisher-Paykel Simplus full face mask and can place it a little higher on my nose which helps keep the air leaking out of my eyes. I also use cloth covers from https://cpapcomfortcover.com/ and modify them a little so they don't press up against my nose. I still have a dry mouth frequently and have used Xylimelts which I just let sit between my teeth and lower lip. Not a perfect solution but it has helped some.

Do you have a medical supply store near by that has a sleep therapist that could help with suggestions for helping with the mask?
