I am 66 years old and yesterday experienced something similar to what I think I experienced once before (about 8 months ago). All of a sudden I started to feel a little faint and dizzy and my eyesight was blurry. I closed my right eye and could see well. When I closed my left eye, there was a grey "curtain" covering the lower half of my right eye. I didn't see anything else other than that "curtain." After a minute or so, it started to discipate from the outside of the eye to the inside and then was gone. I wondered if I was having a mini-stroke. At work this morning, discribing what had happened, one my my employees said it was probably an aura, associate with a migrain. I had no headache or any other reaction or symptom after the vision went back to normal. I have never experienced migrain headaches and not heard of an aura. I have been on the Internet this morning and found lots of information including descriptions of symptoms similar to what I experienced yesterday. This website has been very helpful. Based on what I described, would others who have experienced similar symptoms, suggest that I experienced an aura yesterday. Is this referred to ocular migrain. Should I visit an eye doctor, neuroligist or wait until this might happen again. Are there any natural products that others have found successful in controlling this? Thank you for your help.
