20 20 vision just means you have the vision of the the average person. Youre int centre chunk of the standard distribution curve.
Luckily I too still have good sight, never need gigs and still have 20 20 (+) vision 21 20 (or the other way round).
The Mrs has terrible sight, and the kids app wear glasses also. Though I have never bought pair of gigs for any of them, so have no idea of prices. They seem steep though .
