What Does 20/20 Vision Actually Mean?

While you may have heard the term “20/20 vision” before, do you know what 20/20 vision means for your overall eye health? Advanced Vision Care and Dry Eye Spa in Tucson, AZ, is here to tell you what 20/20 vision means and what conditions can impact your vision score.

What Is 20/20 Vision?

The clearness or sharpness of your vision is referred to as visual acuity. The ideal visual acuity is 20/20, meaning you can see objects 20 feet away that the average person should be able to see at 20 feet. While 20/20 is the standard, you can have even better vision. Some people have 20/15 vision, meaning they see at 20 feet what an average person sees at 15. That said, 20/20 vision does not tell the whole story of your eye and vision health. This score does not consider peripheral vision, depth perception, focusing ability, or eye coordination.

Conditions That Affect Vision

Several eye conditions can impact your visual acuity and lower your vision score, the most common of which are refractive vision errors. These refractive errors include:

•             Farsightedness: Objects closer to you look blurry, while objects further away look clear.

•             Nearsightedness: Objects further away look blurry, while objects up close look clear.

•             Astigmatism: Irregular cornea or lens shape causes focusing problems at various distances.

•             Presbyopia: Age-related refractive error that makes text and objects up close harder to see.

Fortunately, all these conditions are easily treatable with corrective eyeglasses or contact lenses. Our optometrists can detect these vision errors during an eye exam and prescribe lenses to help you achieve visual clarity. We can also refer you to an eye surgeon for LASIK surgery if you prefer a more permanent solution to your refractive vision error.
