Thank you Flamingo @afirefly. I appreciate the feedback. Unfortunately my diplopia was caused by nerve damage related to my AVM(ArteroVenousMalformation). Prisms do not offer help because of the torsion with my eyes. I checked with a neuro ophthalmologist. I may consider strabismus surgery for the eye alignment correction. The surgical adjustment is very small. I run the risk of an over adjustment. In that scenario, the prism will help. So in the meantime I am trying the neuroplasticity on my own. I have looked into the possibility of eye exercises at a doctor’s office. Not only is it costly but very inconvenient to visit the office each time. You would think with vision problems an alternate method would make more sense. I had recommended virtual visits using computer software for the eye exercises. The office is not accommodating at all. Who needs that inconvenience? Oh well, good luck to that business! I had a friend in PA who benefited from eye exercises. It eventually eliminated her diplopia completely. She no longer needed a prism in her glasses! Thank you for your suggestion. My lack of balance stems from the nerve damage created by the AVM. The neuropathy resulted from the last surgery to correct my AVM. I had A total of 3 surgeries. My AVM involved the junction of 5 blood vessels in my brain, namely the cerebellum. It is the same part of the brain affected when one drinks. That is where the lack of coordination or balance comes in. Thanks again, Toni

Hello Flamingo and @avmcbellar and @johnbishop, this is probably a dumb question but can the prisms be removed from the glasses lenses or are they permanent? I have diplopia off and on throughout the day as well as some other vision disturbances like if I'm reading a sentence, that sentence can appear below that sentence although a little lighter. Then I also have the traditional double vision. So, another question, when I am not having those two vision problems, will the prisms in the glasses lenses affect my vision regular at all? If not then it wouldn't matter if they are in the glass lenses permanently or not. BTW, these would be in my prescription glasses that I am asking about. Thank you so much, Sunny flower
