Brock String

Brock String is a vision therapy tool consisting of a string and colourful beads.

What is a Brock String?

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.

What is Brock String Used for?

In Brock String 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.

Benefits of Brock String Eye Exercises

Binocular Vision Improvement

The Brock String is instrumental in enhancing binocular vision, where both eyes work together effectively, crucial for tasks like reading and driving.

Convergence and Divergence Training

With exercises that require the eyes to converge (focus inward) and diverge (focus outward), the Brock String strengthens these essential abilities for near and distance vision tasks.

Depth Perception Enhancement

By focusing on beads at different distances along the string, individuals improve depth perception, vital for accurate distance judgment in daily activities.

Focusing Flexibility

Brock String training encourages quick and accurate focus adjustments, reducing eye strain during tasks requiring frequent changes in focus.

Visual Attention and Tracking

Following beads along the string enhances visual attention and tracking skills, crucial for reading, sports, and driving.

For Whom are Brock String Exercises Suitable?

Individuals with Poor Convergence Skills

Brock String 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.

Children with Vision Developmental Delays

Brock String training is often prescribed for children who exhibit delays in vision development, such as difficulties with eye coordination, convergence, divergence, or focusing abilities.

Individuals with Binocular Vision Disorders

People with binocular vision disorders, such as strabismus (eye turn) or amblyopia (lazy eye), can benefit from Brock String exercises to improve eye coordination and strengthen binocular vision.

Those with Depth Perception Challenges

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

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.

Individuals with Visual Processing Disorders

People with visual processing disorders, such as difficulties with visual attention or tracking, can benefit from Brock String exercises to improve their visual processing abilities.

Students Struggling with Reading and Learning

Students who experience difficulties with reading or learning, which may be associated with underlying visual issues like eye teaming or tracking problems, can benefit from Brock String exercises to strengthen these foundational visual skills.

Adults experiencing symptoms such as eyestrain, headaches, or difficulty maintaining focus, particularly during tasks involving close work or frequent shifts in focus, may find relief and improvement through Brock String vision therapy.

Individuals Seeking Vision Enhancement

Even individuals without diagnosed visual issues can benefit from Brock String exercises to enhance their visual skills, such as eye coordination, focusing flexibility, and depth perception, leading to improved overall visual performance and comfort.

How to Use Brock String?

Learn to see with both eyes simultaneously using the Brock string!

Set Up 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.

Position Yourself

Sit or stand comfortably facing the Brock String, ensuring the entire length is visible without eye strain.

Focus on a Single Bead

Start with the closest coloured bead. Keep it single and clear in your vision while staying aware of other beads.

Shift Focus

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.

Observe Eye Movements

Watch for changes in vision as you shift focus between beads, particularly if you struggle with eye coordination or binocular vision.

Alternate Directions

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.

Incorporate Convergence and Divergence

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.

Repeat and Progress

Regularly repeat exercises, increasing difficulty over time for improved coordination and comfort.
