Distance Eye Chart Instructions
This chart can be used as a screening tool to check clarity of
your distance vision from home. This does not replace an eye
exam with an Ophthalmologist and it can not detect serious
eye problems.
For the best accuracy, have someone assist you when testing your
vision with this eye chart. If you do not have someone to assist you,
you can still perform the test.
1. Open the chart. Check the resolution of your page is set at
100%. To check or change the resolution on the top of your
screen you will see the zoom % change to 100%.
2. Measure 3 metres from your computer screen. This is where you
will need to stand to do the test.
3. If you usually wear glasses or contact lenses for distance
activities such as driving please put them on.
4. Then cover one eye with the palm of your hand, to
completely block the vision of the covered eye. (Do not
apply pressure to the covered eye, as it might affect that
eye’s vision when you test it.)
5. Identify a line on the chart you can comfortably read.
Read the letters on that line aloud. Have your assistant
stand near the chart and record your accuracy.
6. Continue trying to read the letters on each successively
smaller line.
7. Have your assistant stop you when you fail to correctly
identify at least 50 percent of the letters on a line.
8. Record the line number you read up to.
9. Switch to the other eye and repeat.
