I am in the 99th percentile with my eyesight. It is far far better than perfect and my night vision is excellent. The downside is that I cannot see colour as well as most. I am not colour blind, but shades look the same to me.
Basically speaking I can read size 12 font from 4 metres away with the right lighting.
