Pretty much when I was about 8 A 5 year old threw a stick it hit me in the eye and for a few years I had a scar on my eyelid couple of days after the incident I went to the doctors I think I remember him saying I was fine but ever since it happend my right eye's pupil has always been bigger it has never affected me really but It's annoying on sunny days because I can't really see as much where so much light is being let in it's been about 8 years since it's happend and I doubt anything can be done now but is it normal to happen?
