Thanks!

The optician said as I've had this for so long, possibly 20 years, that it's unlikely that my vision will go back to normal. And not to get my hopes up with the prism lenses.

Also, as I have poor eye tracking and abnormal saccades, that also adds to reading problems.

He explained that the convergence insufficiency and poor eye tracking/ saccades are caused by different parts of the brain.

I also have photophobia and don't like going outside much.
