Review on 👀 Enhance Athletic Performance with 10-Foot Brock String - Vision Convergence Training Tool for Strength, Vision Training, and More! by Bashar Shaffer

A simple but very useful eye exercise that will help you focus faster. You will find that you need to focus very little (where the string enters the ball) in order for your binocular vision to be accurate and for the string to look like a V before and after the ball you are focusing on. Binocular vision and target recognition are important in what I do and it really helps. So easy and cheap, do it at home - no wonder no eye doctor has mentioned this in the 55 years I've worn glasses. It helps in any sport where you need to focus on the ball, goal, basket, etc.
