Goalball is an indoor sport played in a gymnasium or hall. It originated in Europe and is the only international team sport for the Vision Impaired played at the Paralympics. Originally it was created to allow people who are blind or vision impaired to take part in a team sport with sighted people. It does not matter what level of vision each person has, as all players have blindfolds and therefore compete at an equal level. The game is played at all levels including social, competitive, local, state and national. In order to play in a national team, players must be legally blind.
