Hi,
I am getting my prism glasses this week, but will also start with vision therapy, my neuro opthomologist say recovery can be anywhere from 6 months to 2 years. She thought that 1 year would not be a bad guess in my case. I am also talking vision therapy online through a company called Vizual Edge. They cater mostly to athletes, but the exercises can be useful for convergence insufficiency and other eye issues.
