Which equipment is commonly used in home vision training?

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

Answer: (C)

Home vision training relies on simple, portable tools that let you practice binocular coordination at home. The Brock string teaches how your eyes fuse two images into one as you focus on targets at different distances, training vergence and the interaction between accommodation and convergence. The peg rotator provides a clear way to exercise eye movements—tracking and rapid shifts between targets—by having you follow rotating pegs, which helps with ocular motor control and binocular coordination. Using both devices together gives a well-rounded home program that addresses both how the eyes move and how they align to keep single, comfortable vision. Vision goggles don’t provide the same structured training for vergence and tracking, so the combination of the Brock string and peg rotator is commonly used.
