It's more like forwards neurelitism, where everyone except you never thought it was important enough to mention that they didn't have visual snow, and then decided to look at you funny because of their poor own communication.
I've had something like that issue from the other side - everyone else in my family wears glasses, but I have 20/20 vision, and I'm afraid I do a pretty bad job of being aware/sensitive towards other people's vision limitations.
It's not a neurological thing, per se, but it's similar in that it's a difference in how we perceive the world. (On another note, I've sometimes wondered if it's possible that my eyes are no more good-at-seeing-precisely than my sibling's, but that my brain is better at interpreting the signals. I can increase the clarity of my vision by a significant
amount just by concentrating in the right way, and it seems to improve with practice; I deliberately practice seeing things clearly in the same way I deliberately practice physical coordination. Neurological, or having an effect on the eye itself? Damn you, science, why won't you tell me!)
