Can you see objects clearly at 20 feet? Kudos!
You have a normal vision. You must have heard quite often about 20/20 vision to determine eyesight which indicates the sharpness and vision clarity. It is the measure of vision acuity. 20/20 vision is actually kind of a certificate saying that you have a normal vision.
Usually, people out of curiosity wish to know how perfect their vision is. Simply stating you’ve got normal vision, doesn’t create an impact but when you say you’ve got 20/20 vision it sounds much effective. But remember it says normal vision, not perfect vision. 20/20 vision does not necessarily mean perfect vision, since it’s just one aspect defining the quality of your vision.

What does 20/20 vision mean?
20/20 vision also known as 6/6 vision in European countries, Australia and New Zealand means to read or view objects clearly at a distance of 20 feet (6 meters).
To perform 20/20 vision test, Snellen chart is used. The chart is placed at a distance of 20 feet from the person who is getting his eyes tested. Your capability of reading the smallest letters on the chart will indicate your vision acuity. However, only the sharpness of your eyesight gets tested.
If a person is able to read the smallest of the letters on the sheet from this distance then the doctor considers it as normal vision. Having 20/20 vision means the light correctly focuses on the retina and provides clear and sharp vision. According to a report, people are even recorded to have superior vision like 20/10 and even 20/5.
20/20 vision is a standard test, if you are unable to read from this distance then you need to go for other test for eyesight ranking ranging from 20/30 to 20/200. With each measurement you have to stand closer to the chart, to understand your vision condition. For every vision condition there are prescription glasses and contact lenses. But this test only determines whether you need glasses or not. There are other aspects that would exactly let you know how can you correct your vision.

- Ability to view close and up close
- Peripheral vision
- Capability of distinguishing colours
- Depth perception
