Test your eyesight

Optometrists measures your vision with the use of a calibrated letter chart. We are all very familiar with the letter charts. Here is an online version of a simulated eyesight test.

To ensure the accuracy of the test there are a few points to note:

  1. Position yourself 150cm away from the monitor
  2. If applicable wear your distance glasses
  3. Normal vision is referred to as 20/20 or 6/6
  4. The legal visual driving requirement for a motor vehicle is 6/12

This chart has been calibrated for a 17 inch monitor at a resolution of 1024x768 or a 15 inch monitor at a resolution of 800x600.


How this chart works.

Use this chart to measure your vision. Make sure you sit at a distance of 150cm away from your computer monitor and your eyes are level with that of the eye chart above. Perform this test one eye at a time, covering up the eye you are not testing.

How far down the chart can you read?

If you are able to read down to:

6/6 line, you have 20/20 vision.
6/7.5 line, it means you have vision that is slightly below 20/20 vision.
6/12 line, you have met the legal visual driving standard.
6/60 line or worse, you are classified as 'legally blind'. You may be eligible for government assistance.
