Earlier today, for about an hour, I had a problem with my right eye - while working at my computer, all of a sudden whenever I moved my eye, I saw spots like you do when you stare into a bright light along with black flashing jagged lines and they moved whenever I moved my eye...the problem cleared on it s own after about an hour - I am currently on meds for diabetes, hbp and high cholesterol, but all these are kept under control. Could this problem be a symptom of eye fatigue from working on the computer for most of the day every day?
