How does blind tennis work?
Blind tennis is actually very similar to normal tennis, but with few adaptations. One of the main ways it is adapted is that the game is played on a smaller court, and a larger sponge ball with bells is used instead of a normal tennis ball. Also, the rackets are smaller and totally blind people are allowed three bounces of the ball, whereas partially sighted players are allowed two.
For totally blind players, the net in the court is lowered by about 7 cm, and tactile markings are drawn around the court to enable the person to navigate it as independently as possible. Visually impaired and sighted people can play tennis together, but sighted players wear blindfolds or masks in order to ensure a level playing field.
