The Visually Impaired Athletes within USA Triathlon are not looking to have advantages or anything, they are looking to have their division broken up into categories so as to level the playing field. Categories such as:
Class B1
No light perception in either eye up to light perception, but inability to recognize the shape of a hand at any distance or in any direction.
Class B2
From ability to recognize the shape of a hand up to visual acuity of 20/600 and/or a visual field of less than 5 degrees in the best eye with the best practical eye correction.
Class B3
From visual acuity above 20/600 and up to visual acuity of 20/200 and/or a visual field of less than 20 degrees and more than 5 degrees in the best eye with the best practical eye correction.
"Leveling the playing field" by requiring an athlete who has lived their entire life with an inkling of vision, and requiring them to "run in total darkness" is completely absurd.
