Advice & Tips: I just got mr 3rd pair of lenses since 11-2010 to address my double vision. My 1st pair was simply a stronger prescription, mainly in my right eye which was significantly weaker. One month later, I was still having double vision, so I had another set of lenses - with horozontal prism. Less than 1 month later, I was still having double vision (however, the images were closer together than before. on 2-1-2010 I now have 2 prism's in each eye (Vertical and horizontal). Thus far, after 1 day, they are working better than the 1st pair of prism's.
Cost: $200+ monthly
