What Does 20/20 Vision Mean?

What is 20/20 vision? 

 

When getting an eye exam for glasses you may have heard the standard for good sight be referred to as 20/20 vision. This is a term used to describe normal visual acuity. Acuity means the clarity and sharpness of sight. In layman’s terms, 20/20 vision means you can see something clearly that is 20 feet away, and you should be able to see clearly. Conversely, if you have 20/80 vision, this means you must be 20 feet away to see something that you should be able to see 80 feet away. 

 

20/20 vision is not a “perfect” vision. 20/20 is only an indication of visual clarity at distance. There are many other factors of sight, such as peripheral vision, eye coordination, depth perception, focus, and color. All of these factors add up to form your overall visual ability. 

 

There are different types of visual deficits. Some individuals can see objects well at a difference but are not able to see objects that are closer. The medical term for this is hyperopia, commonly known as farsightedness. Other people may be able to see items that are close but can’t see objects farther away, known as nearsightedness, this is medically referred to as myopia. 

 

An eye exam for glasses can be used to diagnose your visual acuity. In many cases, the glasses or contacts you are prescribed will assist you with any vision problems you may have. If your vision condition is due to eye disease, your doctor may prescribe medications to treat the condition.
