twenty-twenty vision
Optimal visual acuity
Twenty-twenty vision is normal visual acuity—the ability to see clearly at twenty feet what a person with standard eyesight sees at that distance.
The term comes from the Snellen eye chart used in vision tests.
Figuratively, twenty-twenty vision suggests perfect clarity or foresight: In hindsight, we all have twenty-twenty vision.
Also written 20/20 vision.
