Wierd feeling! > I think this posted "information" is incorrect. I am not a health professional. I presume you mean ocular migraine.

It is caused by not well understood neurological factors after signals from the retina pass through the optic nerve chiasm. Of course, your problem might be something else. Bill -- Ferme le Bush
