That's an interesting idea. I wonder if there is any data on that sort of thing. Anecdotally, though much less dramatically: When my Mom switched from glasses to contact lenses (and received an improved prescription), her sense of happiness and wonder at being able to see the details of tree leaves, etc, is something that I still remember a few decades later.
