Thanks to Mason Curry's book, Daily Rituals: How Artists Work, I was introduced to a quote that reminds me a lot of how we improve vision through vision training or treat visual conditions with vision therapy.
"The more of the details of our daily life we can hand over to the effortless custody of automatism, the more our higher powers of mind will be set free for their own proper work." -Philosopher William James
This quote highlights the importance of repetitive tasks to be automatic (often termed "muscle memory"). Regular practice of a task, albeit in different ways and environments, leads to automaticity. In vision therapy, the sensory-motor system is introduced to new stimuli through 3D tools, large peripheral targets, quickly appearing objects for reactivity and tracking, and are repeated through a series of various techniques to train the visual pathways of the brain to accurately and automatically respond.
Once the visual system has been properly trained, the individual can put more cognitive effort towards the task (such as reading, soccer, writing, etc). Just as James eloquently states, the higher powers of mind will be set free for their own proper work.
