What is 20/20 vision? By William Goldstein on May 16, 2011

20/20 vision has always been considered "perfect vision" by most people. And of course we have all heard nearsighted individuals call themselves blind! But it is hard to know what '20/20 vision' means, and we all know that nearsighted people are not truly blind.
The term '20/20 vision' became known as perfect vision because eye doctors used examining rooms, known as 'lanes' that were 20 feet long! If a patient could see normal sized letters at 20 feet, this was perfect vision. If they needed letters that were twice normal size, they had 20/40 vision, meaning that they were still 20 feet from the letters, but someone with perfect vision could stand 40 feet away and still see the letters.
Blindness is defined as 20/200 vision or worse in both eyes WITH corrective lenses or contact lenses. For this reason, as long as they wear their proper correction, nearsighted patients are not truly blind!
