This relates to the idea that vision loss can also impact brain function https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8739068/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8739068/ I think the underlying mechanism is related to neuron activation in the brain itself because it’s possible that more visual stimulation, regardless of being involved in the task at hand, helps with cognitive functioning in some manner. There are some interesting questions remaining to explore here, like would direct neuron stimulation bypass the pupil size role.
