The correct way to do the test is to
stand at a distance of 3 meters from the chart which has to be positioned
as high as the height of the face in an adequately-lit room.
The test
has to be done one eye at a time by blocking the other eye with one
hand.
If you wear glasses or contact lenses already, these have to be
worn for the test.
The numbers at the right of the letters on the chart
indicate the reading level reached.
If you are able to read down to the
last line, your score is 10/10 which means that both of your eyes have
good visual acuity. This does not mean however that your eyes are
necessarily healthy; the presence of an eye disease is possible even with
good vision.
For this reason, it is important to remember that this
test is not a valid instrument to evaluate the health of your
eyes; it is only a tool to empirically measure your eyesight. It cannot
and should not be substituted for a visit to the eye
specialist.
