Ruler fusion

In this the alignment of the visual axes is encouraged by the use of rulers of various lengths. If you are very myopic a short ruler — say 15 centimetres (6 inches) is easiest to begin with; aim to work up to a 30-centimetre (12-inch) ruler and ultimately to a metre rule (yardstick). Conversely, if you are very long-sighted or presbyopic, start with a long ruler and work down.

For the basic ruler fusion drill, hold the ruler edge-upwards and put one end between your eyes, so that one corner is resting on the bridge of your nose and the other on the lower part of your forehead. Hold the ruler from below, with the fingers of one hand, and align it so that it points straight out in front of you. If you now focus in the distance, the ruler should seem to be making a two-sided tunnel, both sides of which should be equally distinct. Practise bringing your focus back so that the far ends of the tunnel appear to approach each other and meet.
