I woke up this morning, my eyelids were a little sore, like a bruise. When I looked in the mirror, both eyelids were bruised, and right eye also has a bloodclot in the outer white area. I have had no trauma, vision is fine, I feel fine. What can cause this? Could it be from my CPAP mask, I have had the same mask for 1 1/2 years with nothing like this, before.
