20/20

Ideal visual acuity

20/20 describes normal visual acuity—the ability to see at twenty feet what a person with standard vision sees at twenty feet.

The notation comes from eye chart testing: My vision is 20/20 without glasses.

Figuratively, 20/20 means perfect clarity, especially in retrospect: Hindsight is 20/20.

Also written twenty-twenty.
