Certain criteria must be met and equipment made available for athletes to undergo medical classification to complete internationally. These are set out in IBSA?s Medical Procedures.
IBSA has determined three classes in international competition for blind and partially sighted athletes:
B1 - From no light perception in either eye to light perception, but inability to recognise the shape of a hand at any distance or in any direction.
B2 - From ability to recognise the shape of a hand to a visual acuity of 2/60 and/or visual field of less than 5 degrees.
B3 - From visual acuity above 2/60 to visual acuity of 6/60 and/or visual field of more than 5 degrees and less than 20 degrees.
IBSA - committed to Fair Play
As part of its stated aim to guarantee fair play in sport, IBSA is a signatory to the World Anti-Doping Code and has developed and adopted its own Anti-Doping Code to fight against doping in blind sports and protect the health of its athletes.
