My eyesight is over 20/20. Last time I checked (3 years ago, thus now it might be lower) It was 15/10, so 30/20 if you scale up to 20 ft. I didn't know I had a particularly good eyesight 'til I was 17: one day, the slides for a lecture had been misformatted, and I was the only one that could still read them fine.
