Brock String is a vision therapy tool consisting of a string and colourful beads.
Brock String is a vision therapy tool consisting of a length of string typically around 3-4 feet long with three to five small beads of different colors positioned at specific intervals along the string.
In Brock eye exercises, individuals focus on each coloured bead in succession, observing the adjustments their eyes make to maintain single and clear vision. By shifting focus between beads, the eyes improve:
– eye coordination,
– focusing flexibility,
– depth perception, and
– visual processing abilities.

The Brock String is instrumental in enhancing binocular vision, where both eyes work together effectively, crucial for tasks like reading and driving.
With exercises that require the eyes to converge (focus inward) and diverge (focus outward), Brock strengthens these essential abilities for near and distance vision tasks.
By focusing on beads at different distances along the string, individuals improve depth perception, vital for accurate distance judgment in daily activities.
Brock String training encourages quick and accurate focus adjustments, reducing eye strain during tasks requiring frequent changes in focus.
Following beads along the string enhances visual attention and tracking skills, crucial for reading, sports, and driving.

Exercises specifically target convergence abilities by requiring individuals to focus on beads positioned at various distances along the string. This helps strengthen the muscles responsible for bringing the eyes together, improving convergence efficiency over time.
Individuals who struggle with depth perception, which can affect tasks like judging distances accurately, may find Brock String vision therapy helps refine their depth perception skills.
Athletes and sports enthusiasts looking to enhance their visual skills, including visual attention, tracking, and depth perception, can incorporate Brock String exercises into their training routines to gain a competitive edge.






Learn to see with both eyes simultaneously using the Brock string!
Secure the ends of the Brock String at eye level using hooks or clips. Ensure the string is taut and free from twists or knots.
Sit or stand comfortably facing the Brock String, ensuring the entire length is visible without eye strain.
Start with the closest coloured bead. Keep it single and clear in your vision while staying aware of other beads.
Gradually shift your focus to the next bead along the string, maintaining single and clear vision on each bead as you progress. Note any adjustments in eye movement.
Watch for changes in vision as you shift focus between beads, particularly if you struggle with eye coordination or binocular vision.
After focusing on each bead individually, you can vary the exercise by alternating between focusing on beads moving from left to right and then from right to left along the string. This helps engage different eye movements and visual processing skills.
To further challenge your eyes, incorporate convergence and divergence exercises by gradually bringing the beads closer together or moving them farther apart along the string. Practice focusing on beads at varying distances to improve depth perception and focusing flexibility.
Regularly repeat exercises, increasing difficulty over time for improved coordination and comfort.
