The results of an eye chart exam are based on a reading distance of 20 feet To interpret your reading it helps to think of the numbers in feet For instance someone with 20 60 vision can read at 20 feet away what a person with normal vision could read at 60 feet away The Snellen Chart provides a standardized test of visual acuity The chart is placed 6 m 20 feet from the subject The chart consists of a series of symbols e g block letters in gradually decreasing sizes
