The Deluxe Brock String is a 12-foot vision training tool designed to strengthen convergence skills and address binocular vision challenges.

Featuring 5 beads positioned along its length, this instrument helps patients develop proper eye alignment and overcome suppression—when one eye is inadvertently ignored during visual tasks.

Ideal for vision therapy, optometry practices, and clinical settings, the Brock String is an effective, non-invasive method for treating convergence insufficiency and related binocular anomalies.

Its extended 12-foot length allows for progressive training at varying distances, making it suitable for both initial assessment and ongoing therapy progression.

Simple to use and clinically proven, this deluxe version provides reliable performance for professional vision care providers and vision therapy specialists.

Instructions are not included and should be obtained from your eye care provider. Ideal for clinical settings, vision therapy offices, and home-based vision training programs.
