6 years ago, I found out that I have convergence insufficiency, making me see double.. I was given many different exercises, none of which ended up making an impact. Finally, my ophthalmologist said there wasn t anything else he could do, short of surgery. Last week at work, a coworker told me they have a similar issue, and her ophthalmologist gave her a special pair of glasses called prism glasses. She said they help her not see double, better than using regular reading glasses, which I use but they don t help as much as I would like. How do I find out if this could help me, where I could get these, or if an opthalmologist can give me these?
