20/20 vision (острота зрения 1,0 AFilinovTranslation) | |||
20-20 vision (By looking at lots of people, eye doctors have decided what a "normal" human being should be able to see when standing 20 feet away from an eye chart. If you have 20/20 vision, it means that when you stand 20 feet away from the chart you can see what the "normal" human being can see. (In metric, the standard is 6 meters and it's called 6/6 vision). In other words, your vision is "normal" – most people can see what you see at 20 feet. Antonio) |
