5 Bead Brock String Single 12ft
A cord with five brightly colored wood beads used primarily with convergence insufficiency patients to create the feeling and awareness of converging and to normalize the nearpoint of convergence. Also used with esophores to teach accuracy of the vergence response. The patient ties one end of the cord to a doorknob and holds the other up to his/her nose. With the addition of red/green glasses, the patient can practice anti-suppression activities.
