Hi: I experienced small shock-like happenings in my eyes when moving them quickly and also in my head. Most of the time they happened when I was out walking the dog. Anytime SSRI changed - lower dosage for instance, I noticed this happened. I did mention to doctor but she didn't seem to understand, or know anything about it. I think it was the tapering off and now that I am off medication SSRI, no more little shocks. It only lasted about 6 wks. or so. Hang in there, it will pass.
