Blind tennis (tennis for the blind and visually impaired) is a discipline that has long been practiced abroad, known in countries such as Japan, Germany, Great Britain, Italy, Spain and Australia.

Its creator is a blind Japanese Miyoshi Takei, and Agata Barycka introduced it to Poland a few years ago. The rules of this sport are almost identical to those of tennis. However, a special sound ball produced in Japan is used for the game, which is slightly larger and softer than a typical tennis ball. During the game, it can be bounced off the ground three, two or once – depending on the degree of the tennis player's vision impairment. Competitors compete in visual categories: B1 blind people, B2, B3, B4 (people with varying degrees of vision impairment). Ophthalmologists decide on the category.

Blind tennis, like any other sport, primarily affects the development of fitness, but it also helps people with visual impairments in other areas: overcoming the fear of space, orienting themselves in the field, concentrating on the surrounding world, identifying sounds, etc.

The promotion of blind tennis is one of the main activities of the Widzimy Inaczej Foundation, which has been in existence since 2015. The organization runs the Tennis Academy for the Blind and Partially Sighted, where, under the supervision of experienced trainers, people with visual disabilities - adults and children - learn the secrets of the game, develop their skills and look for the best ways to take care of their physical condition and health. Participation in the classes is free of charge, the project is carried out in the following provinces: Lower Silesia, Kuyavian-Pomeranian, Lublin, Łódź, Opole, Lesser Poland, Masovian, Pomeranian, Silesian, Warmia-Masurian, Greater Poland, West Pomeranian.

The Foundation organizes several tournaments a year: Polish championships, the national tournament Rakiety ATNiS, friendly games: Sokole Oko and Tennis in the Center, and additional events such as the St. Nicholas tournament or night games. Polish blind tennis players also travel to competitions abroad - to England, Spain or Italy, and also host players from other countries - so far, four international major tournaments have been held in Poland, including the world championship in 2023.

On December 3, 2024, blind tennis players received state decorations from the President of the Republic of Poland Andrzej Duda for their sports achievements and representing Poland on the international stage. The Bronze Cross of Merit was awarded to: Katarzyna Antczak, Magdalena Giecewicz, Aleksandra Karakula, Kamilla Malak and Michał Stypa. These players brought back bronze medals from this year's world championships in Italy.

The “Tennis Academy for the Blind and Partially Sighted (ATNiS)” project is co-financed by the State Fund for the Rehabilitation of Disabled Persons.
