Indoor court lighting significantly influences player visibility by impacting their ability to track the ball, judge distances, and maintain focus during play. Properly designed lighting ensures even illumination across the court, reducing shadows and glare that can distract players or obscure their view of fast-moving balls. High-quality, bright lights positioned at optimal angles enhance contrast and depth perception, allowing players to react swiftly and accurately. Conversely, inadequate lighting or poor placement can lead to visual discomfort, misjudgment of the ball's trajectory, and an overall decline in performance, making effective lighting essential for competitive indoor sports.
