Members of the International Blind Sports Federation (IBSA) have celebrated the 40th anniversary of the governing body and World Blind Sports Day with various activities dedicated to the development of athletes with visual impairments.

Chile's National Federation, the Federación Deportiva Nacional para Personas con Discapacidad Visual, held an online session to its community to introduce blind football.

In Portugal, Sporting Clube de Portugal's goalball team played an exhibition game against world and Paralympic champions in multiple sports; before later holding an online chat with Brazilian club SESI.

Elsewhere in Portugal, the Portuguese Sports Federation for People with Disabilities worked with the National Sports Association for Visually Impaired People to hold a talent camp for the national team.

Japanese children took part in activities that included trying blind football; while others around the world tried disciplines such as blind cricket and ice hockey.

Triple Paralympian in goalball, Sweden's Fatmir Seremeti, took to Twitter to celebrate World Blind Sports Day, thanking those who got her into sport.

The President of the Brazilian Sports Confederation for the Visually Impaired, José Antônio Ferreira Freire, and the Spanish Federation of Sports for the Blind President Ángel Luis Gómez Blázquez wished IBSA a happy birthday as did the United States Association of Blind Athletes (USABA).

"On behalf of the United States Association of Blind Athletes, our Board of Directors, staff and membership, I would like to congratulate IBSA on 40 years of playing a vital role in growing Para-sports worldwide," said USABA chief executive Molly Quinn.

"USABA is itself celebrating its 45th anniversary this year and we look forward to partnering with IBSA for years to come in continuing to champion sports opportunities for the blind and visually impaired."

As part of IBSA's anniversary celebrations in 2021, seminars on coaching, classification and officiating in blind sports will take place and will be universally accessible.

A coaching platform on visual impairment sports will also be launched.

There are 129 members associated with IBSA, with the governing body being the International Federation for eight sports.

These are football, goalball, judo, chess, powerlifting, ninepin bowling, showdown and tenpin bowling.
