20/20 Idaho: What to Know About Vision Standards and Testing in the State

20/20 vision is often described as "normal" visual acuity, but the term specifically refers to the clarity or sharpness of your sight at a distance of 20 feet in Idaho and across the United States. In clinical terms, 20/20 means you can see at 20 feet what a person with typical refractive accuracy can see at that same distance. It is not a perfect measure of overall eye health, nor does it reflect side vision, color perception, depth perception, or how well your eyes work together. Understanding what 20/20 represents and how it is used in Idaho can help residents interpret vision screenings, eye exam results, and recommendations for corrective lenses or follow-up care.
