My right eye feels like there's something in it off and on everyday. Alot of times when i look at something and move my eyes away, i can see a streak of whatever i was just looking at. Also, i see a purple flourecent color sometimes in my eye. Even when using the computer i find myself squinting my right eye. When this first started, i went to the eye doctor and he told me nothing was in it. I also had corneal abrasion about 6 years ago. Could this be related? Any comments are greatly appreciated, thanks.
