28-year-old Caucasian male, smoker, non-drinker, non-drug-user. Worn contact lenses for 6-7 years, switched to eyeglasses 14 months ago. Problem was noticed approx. 2-3 weeks ago.
Problem is: inside lower left eyelid - 3-4 millimeter bubble, filled with clear fluid. Painless, slightly bluish, palpable - feels semi-soft. No eye redness, no irritation, no effect on vision, no color perception changes, etc. Basically, it's a fluid-filled bubble, that's all.
In the 2-3 weeks since noticing it, the bubble has not grown, has not become painful, and has not changed appearance. But it's not going away either.
Suggestions for further diagnosis and possible self-treatment? Would like to avoid going to hospital due to busy schedule - and lack of medical insurance.
Thanks in advance!
P.S. Sorry for low photo quality - best I can do with a webcam at the moment. Can take higher-quality photo later, if necessary.
