For over six months, I have had blurred vision in my left eye on a daily basis. I have a history of classic migraine with aura, and I have noticed that it appears to get really really worse with conventional migraine triggers - red wine, too much or too little caffeine, etc. Other symptoms also, including dizziness, "drunk" feeling, occasional confusion, some intermittent weakness, but the most prominent symptom is visual. It is rarely painful, though there is pressure at times.
