I have have an eye twitch, but I do not think that it is Blepharospasm (defined as eyelid twitching as far as I understand). I have an uncontrollable twitching of my eyeballs. I usually roll them straight back, but sometimes to the side/horizontal. It is just straight in one direction at a time, not random jittering. I have had this on and off for about 4 years now.
It feels like an itch... I usually feel the twitch coming, but the more I think about it, the more it happens. When I get engrossed in something (a movie, essay, book, etc) I realize that I did not twitch for up to an hour or so. However, when I am stressed either physically or socially, the problem is exacerbated. I often catch myself twitching while catching my breath during basketball/at the gym, meeting new people, or whenever I need to make eye contact. After drinking a fair amount, I later noticed that I hadn't twitched.
I am aware that this is very minor compared to most of the cases on this board. However, this is a major issue for me socially. It is difficult to work in customer service and meet new people when my eyes are rolling back in my head in the middle of a conversation.
Since I was about 8 or 9 years old I have had some type of twitch... usually facial (blinking, squinting, etc), but this is by far the most odd and pronounced.
My vision is not great (-2.25). I wear contacts sometimes and glasses others. The contacts can fatigue my eyes at times, which makes the twitching a bit worse.
I am not sure if this twitching is neurological, psychological, physical (fatigue), or some sort of combination. I have spoken to several optometrists. They just told me to get more sleep and exercise. I get about 6 hours of sleep a night and get half an hour to two hours of cardio a day.
