10 Foot Vision Convergence Training Tool - Train Vision, Improve Strength & Athletic Performance, and More!

The string quality is excellent. The beads move freely enough when you want to move them but stay put where you place them. Simple eye tool that is very well constructed.

When the concussion team told me this Brock rope was going to help my daughter retrain her eyes, I couldn't believe it. It works. The beads are high quality and the rope is soft and smooth. She packs it easily in her back and it never tangles. The beads slide just right. Once rehab is done, we will donate this product to the concussion clinic. It is so well made they probably will have it for years to come.

Simple yet very helpful in exercising your eyes in getting them to focus more quickly. You will notice how you need to focus very small (where the string goes into the ball) to make your binocular vision accurate and for the string to look like a V before and after the ball you're focusing on. Binocular vision and picking up targets is important in what I do and this really helps. So simple and low-cost, do it at home - no wonder no eye doctor ever mentioned it during the 55 years I wore eyeglasses. It will help in any sport where you need to focus on a ball, target, basket, etc.

Order shipped promptly and arrived in good condition.

I'm so thrilled to report that my eyes are beginning to work better thanks to this terrific tool, the Brock String. The customer service is excellent!

Was great for my recovery. Had a traumatic brain injury and it really messed up my vision. This was great therapy

Some beads and some string. The string is a loose weave nylon, so it is stretchy, and therefore hard to draw taunt. Being hard to draw taunt, it is hard to preset the bead distances. Bead ID could be smaller, to increase the friction stop. That said, I'm not willing to invest the time and money to research a better design. This does help focus, and I do use t daily.

Our child’s physical therapist recommended these as they are working on vestibular issues right now. This continues to be a challenge for my child and we are thankful we were able to find this for such a great price.
