What Does 20/20 Vision Really Mean?

Have you been told that you have 20/20 vision, but are unsure of what it means? Our optometrist at Fountain Valley Optometry in Fountain Valley, CA are here to help explain this common measurement of visual acuity.

What is 20/20 Vision?

20/20 vision is a measure of how well you can see objects from a distance. It indicates that you can see an object clearly that is 20 feet away, which is the standard distance used for measuring visual acuity.

The first number in the measurement refers to the distance from which you can see an object, and the second number compares your vision to the average person. For instance, if you have 20/50 vision, it means that what you can see from 20 feet away is what the average person can see from 50 feet away.

It is important to note that having 20/20 vision does not necessarily mean that you have perfect vision. There are other factors that contribute to overall eye health, such as depth perception, color blindness, and other issues, which an optometrist can evaluate during an eye exam. Some people even have better than 20/20 vision, such as 20/10 vision.

How Does an Optometrist Measure Visual Acuity?

Eye charts are a common tool used by optometrists to measure visual acuity. The chart consists of rows of letters that decrease in size, and during an exam, you will be asked to read them from 20 feet away. The smallest line that you can accurately read determines your visual acuity. It is important to remember that your visual acuity can change over time, and regular eye exams are recommended to monitor any changes.
