An device for maintaining a moisture cavity surrounding the eye of a user is provided which employs a flexible body configured for positioning on the face of the user with a cavity defined by a curved sidewall positioned in front of each eye of the user. The cavity prevents communication of the exterior atmosphere with the air within the cavity and thereby maintains an environment in each cavity suitable to maintain natural eye moisture. The body is configurable to engage to the face of the user concurrent with the engagement of a CPAP device and may be adapted for engagement as part of the CPAP device. Curved sidewalls forming each cavity are optically correct and transparent to maintain the vision of the user during use.
