I am legally blind without glasses. I'm -575.
I learned to have very sensitive tactile fingers. I can find anything in the dark anywhere in my room with touch, and it's really fun for me. I know what everything is in any mixed bag of random items anyone gives me, if they dare. A great game.
. I can hear when the walls or large obstructions I walk by are located when walking by them in the dark. How fluid changes to a higher pitch as it fills in a cup, etc., and the finger trick to confirm when to stop filling something, if my fingers aren't too cold.
This is because I wasn't visually corrected for a while when I was young. I learned how to feel my way through stuff. There's a long story to that. Let me just hint with, "A cobbler's children don't have shoes".
But I think my visual deficit actually heightened so many other things in my life that well-seeing people simply have no idea about, or don't pay attention to. Like touch, sound, and tactile memory. Of course, sounds and smells are important, but just for not being able to see when I want to if I misplaced my "eyeballs", I'm thankful I can quickly do a hand scan.
