Conducting the Snellen Vision Test

Conducting the Snellen Vision Test

Make sure the room is set up in the correct way.

The test is conducted exactly 4m from the child and at the same level as the child’s eyes. Measure 4m from the child with the tape measure and mark on the floor with a piece of masking tape.

Ensure that the Snellen test card is at the height of the child’s eyes when the child is standing.

Make sure the child is not facing a window or other bright light source that could make the chart difficult for them to see.

NOTE: the test card must be in a matte finish. This is to ensure that there are no reflections on the card during the test.
