What does 20-20 vision mean?



“20/20 vision” refers to normal vision. This is the vision which allows the majority of people to read an eye chart from a distance of 20 feet away. The sharpness of eyesight clarity is measured by an eye chart. A traditional eyechart has a number of randomly accumulated letters that vary in size in no apparent sequence. The term 20/20 indicates the distance in feet from the chart (top number) and the bottom displays the distance from which a person with normal eyesight can read the line.
