A few recent posts have gotten me fired up about the idea of potentiation and how it’s probably the neural mechanism responsible for what we generally describe as merging double vision by looking intently.
The thing is, it’s not just about merging double or multiple images. In fact, it’s more about letting the brain filter out the parts you don’t want to be bothered with, and emphasize the parts you do want to see.
Actually, I think this how I survived so long with my drastic undercorrection. Sure, text was mostly unreadable, but I could see simple shapes even if they were small and distant.
Think fighter pilot vision. You make the most of your current acuity and focus by letting the brain filter out the information.
And if anything, the brain maybe impacts the eyes positively as well, improving the actual focus.
By the way, I don’t like trying this for near vision. Anytime I did, it caused more strain for some reason. Anyone else had a similar experience?
