What Does 20/20 Vision Mean?

Optical terms like "20/20 perfect vision" are confusing. Words like these can be perplexing to people like us, and we frequently require a simplified explanation to fully comprehend the eye state. Don't worry, we're here for the right reason. 20/20 vision is normal, adequate and of course, a good thing. Let’s delve deeper for more information.

A Brief on 20/20 Vision

20/20 vision simply means normal vision clarity; if you have 20/20 vision, you can see normally up to a distance of 20 feet (what should normally be seen at that distance). The concept of 20/20 vision is mostly used in the United States, whereas in the United Kingdom, it is 6/6 vision, which is similar to 20/20 vision. If your vision is less than 20/20, all you need to do is wear glasses or contact lenses and achieve clarity.

There is a widespread misconception that having 20/20 vision means that you possess perfect vision. It only refers to your visual acuity (or clarity of vision). It means that you do not need any prescription. You also need to keep a check on your peripheral vision, focusing ability, colour distinction, and many other things. To enjoy an extraordinary vision, make sure to contain all these boxes to claim perfection in eyesight. For example, people with perfect visual acuity sometimes wear blue light glasses to protect their eyes.

What Are the Causes of Less than 20/20 Vision?

Some of the causes of less than 20/20 vision typically include:

  • Hyperopia- farsightedness
  • Myopia- nearsightedness
  • Amblyopia
  • Astigmatism
  • Cataracts
  • Diabetic retinopathy
  • Age-related macular degeneration
  • Glaucoma

How to Measure 20/20 Vision?

determine your vision through the Snellen Chart

In order to measure 20/20 vision, the first thing that you need to do is visit an eye care provider. They will ask you to look at a chart (also referred to as Snellen Chart) and read the letters written on it. Cover one eye and read with the other one- use both left and right eye to read the letters. After that, try reading with both your eyes.

These simple eye tests will allow the eye care professional to learn about your perfect or impaired vision. By providing prescriptions, these professionals will make sure to guide you through thick and thin. These visual acuity tests are non-invasive and extremely simple- they are mainly performed by an optometrist, optician and ophthalmologist.

If your eyes don’t meet the 20/20 standard, you can rely on:

  • Prescription eyeglasses
  • Corrective surgeries
  • Eye drops
