Glad you're better, amellis. Here's my story, and being a doc I should have known a bit more.
Contracted a nasty conjunctivitis in September in France (hah, blame the French again!), soon spreading to both eyes. I wandered through the Prado Museum in Madrid unable to see a thing!
Upon return home, likely spreading it throughout the aircraft on my way, my ophthalmologist took one look at my nasty condition and shrieked "you've got adenovirus conjunctivitis!" Having been on a week of antibiotics both oral and local by then, I guess that was the obvious diagnosis. Expect three weeks, says he, and he was correct. I spread it to my wife also, for which she was very grateful.
In doing a little research, the bottom line: viral conjunctivitis is extremely contagious, you almost never know where it came from, there is little or nothing to do in treatment except lubricating drops for symptom relief, and while it is going on you can't do squat.
Glad you seem to have gotten out of it in a shorter time!
