For me, it was instructive how long it took anyone to notice that I was *severely* nearsighted. As most know, 20/20 is considered normal vision. -1 diopters = 20/40; -6 diopters = 20/500. My eyes are -8.50 & 9.50 diopters. Nobody noticed until I was in the 3rd grade.https://twitter.com/EricRWeinstein/status/1169484481369010181 …

I wasn't as severely nearsighted, but when I got my first pair I made my parents take me back. Tried to explain to the doctor there was something wrong. Stuff was too sharp, like there were outlines around everything.
