Around twenty years ago, I recall suffering from a severe bout of conjunctivitis - and yes, in my good eye; it was itchy, sore, red-eyed, and my vision became blurry.
I had had a bad headcold, and my sinuses (which were an endless source of inconvenience for decades) became infected, and - I'm not quite sure how it happened - they, in turn (or, so I was informed subsequently) somehow infected my eye.
Anyway, I was teaching at the time, teaching Russian and Soviet history to a class of very good (and motivated, and interested) students, in an ancient and venerable university, and I vividly recall a sudden, startling, entirely unexpected, sharp jab and serious stab of pain in my eye - I was speaking at the time, and almost cried out with startled shock and pain, it was like a sharp sting in my eye - I remember suppressing that - and also almost lost my train of thought, during my own lecture.
Initially, I thought it was a stye, - I'm prone to them when stressed, or run-down - or that I had somehow managed to get something in my eye.
But no: A day later, (I had assumed that it might have cleared up overnight, but, it didn't), visiting the university's medical facilities (I could hardly see, let alone read by then, for everything was blurry), - they diagnosed "severe conjunctivitis".
Antibiotics and drops (both prescribed) cleared it up in a couple of days, but it was pretty unpleasant at the time.
Best of luck with it,
@Clix Pix; I can well understand (and empathise with) your concerns.
