A common way to look at the brain and visual system in performance vision is similar to how we look a computer- specifically hardware and software. The “hardware” refers to aspects such as visual acuity, optic nerve function, contrast sensitivity and color vision. The “software” component is what we actually do with the information collected, namely how we perceive that information and what our actions are.
Performance vision is used to train and improve both of these functions. In training the “hardware”, we make sure an athlete is maximizing their full visual acuity, contrast sensitivity and flexibility of focusing. We also use technology to improve the “software” through perceptual-cognitive training, improving attention, and reaction/visual search strategies in order to help the brain control the eyes at a higher level.
