Vision levels

There are 3 different vision levels that apply to blind sport internationally. Australia has a fourth category. Details of these are shown below:

B1 - Totally Blind

These are players who have no sight at all.  To ensure fairness an occlusion device i fitted to the eyes to ensure all players are totally blind.

B2 - Partially Sighted

These are players with partial sight, on the Snellen eye system of testing they see less than o equal to 1/60.  This means that for a fully sighted person being able to see 60 metres, the blind bowler can only see 1 metre.

B3 - Partially Blind

These players have the best sight for international competition.  They are all still legally blind, but fall somewhere between 1/60 and 6/60.

B4 - Partially

These players have the best sight and are not legally blind and not accepted in all sports.  Eyesight is somewhere between 6/60 and 6/24.
