The field of view design of tennis sunglasses needs to meet the special requirements of tennis, mainly enhancing the visual experience from three aspects: lens curvature, frame structure and functional optimization.
1. Lens curvature and field of view expansion
Arc design: In tennis, it is necessary to quickly track a ball flying at high speed. The lens adopts a targeted arc design to expand the lateral field of vision and reduce blind spots. For instance, some professional lenses optimize the curvature so that the wearer can still clearly capture the trajectory of the sphere when turning their head or looking sideways.
Optical correction: The arc design should avoid image distortion to ensure that the shape of objects at the edge of the field of view is not distorted and to prevent visual errors from affecting the judgment of hitting the ball.
2. Frame structure and field of vision guarantee
Lightweight and fit: The frame is made of lightweight materials (such as carbon fiber, TR90) and the nose pads and temple designs are optimized to ensure that the frame remains stable and does not slide during intense exercise, avoiding vision obstruction due to displacement.
Anti-fog function: Frequent movement during tennis can easily cause the lenses to fog up, affecting the clarity of the field of vision. Anti-fog coatings or ventilation designs can reduce fog interference and ensure visual stability during long-term movement.
3. Function optimization and field of view adaptation
Contrast enhancement: The tennis court is mainly green. The lenses enhance the transmittance of the yellow light band (such as amber lenses), which can improve the recognition of yellow tennis balls and optimize the overall color contrast at the same time, making the field of vision clearer.
Anti-glare: Polarized lenses can filter out the reflected glare from court lights or sunlight, reducing visual interference. Especially in outdoor or night-lit courts, they can significantly enhance the comfort of the field of vision.
4. Practical application of field of view range
Dynamic tracking: The expanded field of view enables the wearer to cover a larger area without frequently turning their head, facilitating the prediction of the opponent’s hitting direction or the adjustment of their own position.
Safety: The stable frame and anti-fog design reduce the risk of collision or slipping due to limited field of vision, enhancing sports safety.
