A person who has 20/20 vision does not necessarily have perfect vision in all regards. 20/20 vision simply means you have normal clarity of vision (called “visual acuity”) when looking at objects at a distance of 20 feet. In contrast, someone with 20/100 vision has to be 20 feet away from an object in order to see it as clearly as a person with normal visual acuity does at 100 feet.
Someone with 20/20 vision may still have problems with other vision factors, such as:
- Depth perception
- Side vision (peripheral awareness)
- Color vision
- Eye coordination
- Focusing ability
While 20/20 vision is considered excellent for a human being, many types of animals (including birds of prey) have 20/10 or better natural vision. Some people who undergo LASIK eye surgery experience 20/15 or better visual acuity.
If you are interested in taking advantage of LASIK eye surgery to correct your vision, please contact an experienced ophthalmologist in your area today.
