Tennis: Ball tracking, distance and open space
Tennis commonly involves longer trajectories, powerful baseline rallies, high serves and broad lateral movement. Prescription lenses should provide comfortable distance correction while allowing the player to scan the opposite side of the court, follow the ball above the head and transition quickly between baseline and net.
On outdoor courts, changing sunlight, shadows and glare may affect comfort. Lens tint should be chosen with the actual court orientation, surface and playing schedule in mind. For indoor matches, sufficient visible light transmission generally matters more than strong sun filtering.
During serves and overheads, frames should remain stable when the head tilts sharply upward. Low weight, balanced pressure and properly fitted temples can reduce the need to push the glasses back into place.
