"The old saying goes that ghindsight is 20/20. Many people think that
20/20 vision supposedly means perfect, but it just means gnormal.h In
the ophthalmologic sense - to have 20/20 vision means that when you stand
20 feet away from an eye chart - you can see what the gnormalh human
being can see from 20 feet. (in metric itfs called g6/6 vision). So
what is 20/200 vision? In the United States, 20/200 is the cutoff for
glegal blindness.h
In the figurative sense, g20/20 Hindsighth suggests that if we look
backward, we have full information and everything is suddenly so obvious,
regardless of what we thought in the past as things happened and we had
imperfect knowledge. Usually, the term is sarcastic in response to
criticism of a decision and implies that the critic is unfairly judging
the situation."
