Lately I have been having a lot of trouble focusing especially my right eye on things. I usually use my right eye to line up things when I'm woodworking and making cuts and stuff. Sometimes when I'm trying to follow a line it and the saw blade both seem to disappear. Besides being disconcerting it's down right dangerous. I know amantadine can cause some problems, but I'm beginning to have trouble just opening my right eye. Anyone have problems simular to this?
