📜 Origin
The phrase draws on the concept of 20/20 vision, a standard measurement indicating normal, perfectly clear eyesight at a given distance. Applying this to “hindsight" (the understanding of a situation only after it has already happened) creates a vivid metaphor for how clearly we can “see" past events and decisions once the outcome is already known. While the sentiment behind the phrase dates back centuries, the specific “hindsight is 20/20" wording became especially popular in American English by the mid-20th century, closely tied to the widespread use of 20/20 as a benchmark for ideal vision in eye exams.
