To See vs. To Look in Tennis: Visual Performance Beyond 20/20 Vision

Key Points

• Harnessing Visual Performance:

• • Looking involves both motor control (eye movements like saccades, smooth pursuit, fixation, reflexes) and sensory function (image clarity, visual acuity, binocular fusion, depth perception).
• • Seeing is different from looking - it's the cognitive side of vision, where the brain processes and interprets the visual information. This is what we refer to as neurovision.
• • Having 20/20 vision does not guarantee strong visual performance: visual acuity is only one part of the overall system.
• • True visual performance requires considering all elements together: refraction and corrective needs, the brain's ability to process information, and functional aspects like coordination and response.
