Avoiding Tunnel Vision
The part of our eyes that process information are primarily made up of rods and cones. Thinking back to basic anatomy class, rods are responsible for low light scenarios and mainly detect shape and movement, while cones are responsible for determining color in brighter light. Understanding the basic anatomy of the eye will help explain what we call Periphery Processing. One of the biggest benefits we hear from our players is the amount of information they're able to process in such a small time period. This processing leads the athlete to expand their periphery and limit tunnel vision.
Basketball is littered with examples of players needing to expand their Periphery Processing. On defense especially, the off-ball defenders have the biggest opportunity to make a play and disrupt the offense. Seeing a pick coming and recognizing where the ball handler wants to go, gives the defense such an advantage! While we focus on visual acuity, contrast sensitivity, etc. the processing of information becomes second nature giving the rods in your eyes a heightened sense of awareness. This ability in turn allows the athlete to expand their Periphery Processing and see more than what they did before the training.
