Olsen, you are the only person to mention Amantadine's effect on vision. My neurologist told me to have my eyes checked when I said I had strange visual reactions from Amantadine. I had just had my eyes examined at the time.
At 100 mg per day I see only very faint green and pink tracings in the bathroom sink and in the tub. At 200 mg per day I saw green and pink paisley lace patterns on white walls and ceilings. The patterns were very clear and visible, very symmetric and very beautiful - but disturbing all the same. I hope your husband's visual disturbance was pleasant enough too.
