The onset was sudden. I used some Bausch &Lomb Opcon A drops around an hour ago (no uneven pupils). I went outside to do some yardwork, my vision became burry and I check the mirror to see if I had got something in my eye when I noticed the freakishly dilated pupil.
I check a little while ago, and I saw that it is not fixed. The iris does expand and contract a little with light.
