If you use a CPAP machine then you likely have experienced 'CPAP dry eye'.  The common symptomology is patients with scratchy, irritated eyes on waking if mask fit is not perfect or a nighttime shift occurs.

CPAP dry eye is not a real 'diagnosis'... but certainly is a common clinical observation.

Beyond ensuring that mask fit is optimal, for CPAP dry eye, I recommend that patients use either:
Ocunox night-time ointment with Vitamin A or I-Defence gel.

Both are non-preserved and when used just before bed, prevent much of the overnight evaporation that causes the morning discomfort and redness.

Both gels (I-Defence less) cause some blurred vision so only evening use is recommended.
