Think you have 20/20 Vision?

What do you think of when you hear "20/20" vision?

Most people think "normal, healthy" vision. Is that really the case?

Although having 20/20 vision means you can

Here's where the 20/20 designation comes from: By examining many people, eye doctors have decided what a "normal" human being should be able to see when standing 20 feet away from an eye chart. If you have 20/20 vision, it means that when you stand 20 feet away from the chart you can see what the "normal" human being can see. (In metric, the standard is 6 meters and it's called 6/6 vision). In other words, if your vision is "normal" -- most people can see what you see at 20 feet. But having 20/20 vision is not an indicator that you or your child's eyes are healthy.
Most people do have healthy eyes, but it is critical that we carefully evaluate the health of your eyes every time you have an eye exam.
