What Does 20/20 Vision Actually Mean?

If you’ve ever had an eye exam, you may have heard your optometrist discuss 20/20 vision. But what exactly does that mean? We have the answers at Eyecare Professionals in Mandan, Hazen, and Washburn, ND. Our team of experienced and knowledgeable optometrists provides a wide range of eye care services and treatments. Here is all you need to know about 20/20 vision.

What Is 20/20 Vision?

20/20 vision is a term that refers to normal visual acuity (or sharpness and clarity) measured at a distance of 20 feet. This means you can see objects 20 feet away, corresponding to the Snellen fraction 6/6 in metric units.

How Is 20/20 Vision Measured?

The most common way to measure 20/20 vision is using an eye chart. This chart with letters, numbers, and symbols decreases in size as you go down the page. When having an eye exam, you will be asked to stand 20 feet away from the wall-mounted eye chart and read the letters aloud. Then your optometrist will measure the minor line of text you can read accurately and record it on your chart.

Is 20/20 Vision Considered Perfect Vision?

Having 20/20 vision does not mean your eyesight is perfect. It only means you can see clearly at a distance of 20 feet, and it may not indicate other aspects of your eye health or whether you need eyeglasses or contact lenses for different visual tasks.

Is 20/20 Vision Common?

20/20 vision is considered regular or average, meaning it’s standard. Most people can see clearly at a distance of 20 feet and do not need corrective lenses for distant vision. An optometry exam is the best way to know if your vision acuity falls in the normal range or if you need glasses or contact lenses.
