I suffered from strabismus while an infant and got surgery at 5. For some unfortunate reasons, I did not get sufficient vision therapy and this turned into amblyopia (lazy eye).

20 years later, as an adult, I had weekly vision therapy for close to 1 year (once a week). All the other patients where kids less than 10 y/o. Although it is considered very hard (or impossible) to correct amblyopia in adults (https://en.wikipedia.org/wiki/Amblyopia#Treatments), my doctor was very open minded and we tried a lot of different exercises with more or less success.

I made some progress so the brain can learn some tricks. For example, I learned to switch my point of view from one eye to the other. I can also force my brain to see from both eyes at the same time though I then see double and the images are not aligned and the lazy eye's image is darker.

At the end, I stopped active therapy for two reasons. First, because I was scared that I would end up in a state where I would see double all the time and not be able to control it anymore. I know it is not very pragmatic but as talanvor said, I will not risk loosing my one good eye. Second, because it was becoming very expensive and the insurance was not ready to cover this kind of treatment for adults.
