Description
Have you ever heard someone say they have a "20/20 vision"? It's a way of describing how well you can see. Let's break it down in simple terms. What is 20/20 Vision? Having 20/20 vision means that when you stand 20 feet away from the eye chart, you can see the same letters or symbols that a person with normal vision can see at that distance. In other words, your vision is considered normal. How is Vision Measured? The first number, 20, represents the distance in feet between you and the eye chart. The second number, also 20, is the distance at which a person with normal vision could read the same line you can see clearly. If your vision is, for example, 20/40, it means you need to be 20 feet away to see what a person with normal vision can see at 40 feet. If you have 20/100 vision, it means you must be at 20 feet to see what someone with normal vision can see at 100 feet.
