In spite of it’s modest appearance, the Brock String is a powerful tool for developing vision. It consists of a sturdy string strung through a number of brightly colored beads. The therapist guides the client through varied exercises that require the beads be viewed at varying distances, and generally in some sort of sequence.
A typical Brock String with three beads. Other strings are longer with more beads.
The Brock String inexpensive to make and yet it becomes the basis for some wonderful activities, helpful in developing visual skills. Brock Strings are used to
- Create awareness of space and depth.
- Increase the range of motion of the eyes, especially inwards and outwards movements (convergence and divergence, respectively).
- Increase accuracy and range of targeting.
- Improve scanning ability.
