bubble on eye

I have a clear watery bubble on the white part of my right eyeball.  It is not painful,just annoying.  It feels like I have something stuck in my eye.  I tried to touch it to see if it would wipe off,  although it looks and feels like water it didn't budge.  This is about the 5th time this mysterious bubble has appeared on my eye...and it  always goes away with time. I haven't had any surgeries or trauma to my eye of any kind.   the only thing out of the ordinary is that the same eye waters excessively every once and awhile.   Is this a concern, or something not to worry over.   One more thing, my vision is pretty blurred.

Only the last sentence is alarming. Blurred vision deserves a diagnosis. See an Eye MD physician-ophthalmologist to determine why your vision is not clear.

The "bubble" you are describing most likely is a conjunctival cyst. They come and go. They are benign. If they get big enough and don't "go" then the Eye MD can drain it simply and painlessly in the office.
