I read a lot a information from a neurological opthalmologist at one time who was a PD sufferer herself. She talked about some sort of prism that could be fitted to a person's regular glasses that helped some. She also suggested putting an opaque strip (like Band-Aid) across the bifocal part of one eye. This did not help my Dad in the least. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
