More about twenty-twenty
Twenty-twenty “keenly or acutely perceptive,” as is often remarked of the advantages of hindsight, has its roots in vision. In ophthalmology, twenty-twenty means “having normal visual acuity,” and is based on the Snellen chart developed by Dutch ophthalmologist Herman Snellen in 1862. Many will recognize this chart as the array of letters one reads when taking an eye test. Snellen calculated fractions to determine visual acuity, or the clarity or sharpness of one’s vision, and twenty-twenty refers to the fraction that corresponds to what someone considered to have normal vision can see at a distance of 20 feet. By the middle of the 20th century, twenty-twenty was a jazz term meaning excellent. By the early 1960s, the disillusioned, regretful expression twenty-twenty hindsight had emerged in the business world.
