What does having 20/20 vision mean?

We hear the term 20/20 vision all the time, there’s a popular news program that uses the term, and there even used to be a video store with the same name.  But what does it really mean and how does it relate to eye care?

The term 20/20 vision refers to visual acuity, and is a measure of your central vision’s ability to see shape details from twenty feet away. It is considered “normal” vision, and other levels of vision are compared to this measurement. If someone’s vision is 20/40, this means you must be at 20 feet in order to see what a person with normal vision can see at 40 feet. Having vision of 20/200 means that a person with 20/200 vision must be 20 feet away from an object that a person with normal vision can see from 200 feet away. The 20/200 level of vision is also the measurement for being legally blind.

A lot of people think seeing 20/20 means you have perfect vision, but it doesn’t. This measurement doesn’t take into consideration many aspects of vision such as peripheral vision, depth perception, or your ability to see different colors.
