Ever since a couple months ago when I got sick, I've had this white goo in my eye. Sometimes it's even a greenish tint, like phlegm. It's irritating, but not anything more than the fact that I feel something there and once in a while, like while I was still sick, there was large enough portions of it that it would cover my pupil and I wouldn't be able to see through it till I used a mirror and got it out. It only happens in my left eye, and it's become less and less over time, but I've just been wondering if I should do something about it since it's lasted so long.
