| What does 20/20 mean? | |
 |
Most people use this to describe perfect eyesight. Actually, it means that you can see clearly at 20 feet what should normally be seen at that distance. By contrast, if you have 20/100 vision, you must be 20 feet away to see what a person with 20/20 vision can see at 100 feet. |
