What is 20/20 Vision?

Most people may not know the Snellen Chart by name, but they recognize it when they see it. Snellen Charts are standard visual acuity tests that display letters in graduated sizes, helping to assess whether a patient has 20/20 vision or another level of visual acuity. If you're in the Columbus, OH, area and need an optometrist or an eye exam near you, contact our team at Beal Eye Care to schedule an appointment.

Your Eyes and Refractive Errors

Light entering your eyes is bent, or refracted, as it passes through the cornea and lens. In individuals with normal vision, the light is focused directly on the back of the eye, or retina. However, for those with irregularly shaped corneas or lenses, the light is distorted and comes into focus either too early or too late, resulting in a blurry image.

What Does 20/20 Vision Mean?

The ciliary muscles stretch the lens in our eyes, allowing us to focus on objects at various distances. When someone with normal vision looks at an object 20 feet away, the ciliary muscle is relaxed, which is why 20 feet became the standard distance for assessing visual acuity. In countries using the metric system, this is referred to as 6/6 vision, as they base the measurement on 6 meters rather than 20 feet.

While having 20/20 vision is often considered ideal, it is only one measure of visual ability. The 20/20 standard does not account for depth perception, peripheral vision, eye coordination, or other essential visual skills required for everyday tasks. So, while 20/20 vision is important, it does not represent the full scope of your eye health.

Common Treatments for Refractive Errors

Refractive errors, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, are common but highly treatable. People with refractive errors often find relief using eyeglasses, contact lenses, LASIK surgery, or other corrective interventions, depending on the level of visual impairment.
