 While historically the English National Association of Visually Handicapped Bowlers had included limited field of vision as a consideration for this class, it was dropped because this vision issue did not impact ability in bowls.For swimming, the classification was eligible to compete at the 2012 Blind Sporting Association Australian Swimming Championships.There is an equivalent to this classification in blind archery known as VI Open, which is open to people with visual acuity of less than 20 degrees.
