Equipment that may be used in home training includes:

• A. Brock string & Peg rotator
• B. Brock string
• C. Peg rotator
• D. Vision goggles

Answer: (A)

In home-based binocular vision therapy, using simple, portable tools that directly challenge vergence and ocular motor skills is key. The Brock string provides a clear, foundational exercise for convergence and binocular coordination. By guiding the patient to focus on beads placed at different distances along a string, it trains the eyes to work together and maintain single vision as the demand on vergence changes, while also helping reveal suppression or diplopia patterns.

The peg rotator adds a dynamic element, rotating pegs so the patient tracks andFocuses on targets that move around in space. This strengthens smooth pursuit and fusional vergence under varying positions and demands, which complements the static, near-to-far work of the Brock string.

Using both tools together gives a broader, more versatile home program: one builds steady, foundational vergence control, the other adds real-time ocular motor training with moving targets. Vision goggles alone don’t provide the same targeted vergence/oculomotor practice for home training, as they’re more about occlusion or filtering rather than structured binocular coordination exercises.
