Hello my girlfriend has been having problems with her eye lately. She says every couple of months for a short period (like a week )her one eye shakes violently. only one eye will do this but ive looked at her eyes when this happens and her eye isnt moving so it has to be something with her brain or inside her eye, not with the eye muscles. she says her opposite eye(one that doesnt shake) gets tired halfway though the day trying to compinsate for this. no idea what to do she went to the doctor a few months ago and they gave her reading glasses since she has a stignitism but now the shaking is back in her eye and its not because she reads..
