Can water wash away corneal edema?

This has been going on for 2 years (that I’m aware of), during those years I’ve been to the ophthalmologist and optometrist 3-4 times.

This may be weird question just paranoia.

When I wake up sometimes, I notice lights have halos around them/blurry vision but absolutely immediately upon splashing my eye with water, within seconds they completely disappear. I read corneal edema is worse when waking/causes halos - I’m wondering if I’m washing dry eyes or if I’m washing away corneal edema. And if it were corneal edema it would last far far longer than a second yes?

Water on the cornea is not good and makes cornea edema worse. More likely is that at night your eyes dry, when you get up it is more the blinking than washing your face with water that makes them better.  This is especially a problem in people that sleep with fans in the bed room,  people with dry eyes (mostly female).  Try artificial tears rather than water if you want something to put ON the eye.
