CPAP Dry Eyes or Red Eyes: Mask Leak Fixes
Waking up with dry, red or watery eyes on CPAP is a classic sign of air leaking from the top of your mask toward your eyes. Refitting the mask, replacing a worn cushion or changing mask size or type usually fixes it.
Signs
- Dry, gritty or burning eyes in the morning
- Red or swollen eyelids
- Watery eyes
- Feeling air blowing at your eyes
Common causes
- Leak at the top of the mask
- F&P says waking up with dry, irritated eyes is a sign of excessive mask leak.
- Mask too tight or too loose
- F&P notes eye irritation often comes from a mask fitted too loosely or tightly.
- Worn cushion
- Old cushions lose their shape and seal, leading to leaks.
- Wrong size
- A mask too large at the nose bridge often leaks upward.
Fixes to try, easiest first
Reseat the mask with air on
Turn the air on, lie down, pull the mask away and let it settle back. Then adjust the top straps.
Test the fit in your sleep position
F&P recommends testing the fit lying in the position you normally sleep in.
Do not overtighten
Tightening too much can fold the cushion and create new leaks. Aim for the loosest fit that seals.
Clean and replace your cushion
Wash the cushion daily to remove skin oils. If it is old, stiff or torn, replace it per your schedule.
Try a different size or style
If leaks continue, F&P suggests you may need to replace the mask. Nasal pillows or under the nose masks keep the seal away from your eyes.
See your eye doctor with your clinician
If irritation continues even after the leak is fixed, see an eye doctor.
See your doctor or eye doctor for eye pain, discharge, vision changes, or redness that lasts after you fix the leak. Contact your equipment provider if you cannot stop the leak yourself.

Frequently asked questions
Can CPAP cause dry eyes?
Yes, usually from air leaking at the top of the mask toward your eyes. The Sleep Foundation notes poor seals can direct air toward the eyes.
Which CPAP mask is best if I get dry eyes?
Masks that seal under the nose, like nasal pillows or under the nose full face masks, keep air away from the eyes.
Should I use eye drops for CPAP dry eyes?
Lubricating drops can soothe your eyes, but fixing the leak is the real cure. Ask your eye doctor about drops if irritation continues.
