...better than 20/20 vision?

[Rye]

It is possible to have better than 20/20 vision (naturally and with corrective lenses). It would involve the latter number being less than 20 (20/15, for instance). It just means you have even better eyesight than normal.

"20/20", from what I've heard, is not some perfect vision that cannot be surpassed; it's just what's normal for human vision. Many animals, for instance, have far superior vision.

Raistlin has the most superior vision of all.

No way, he's totally blind. But my vision is even worse than his, and I'm 3 years younger.
