For the first time, Paralympic judo was divided into two classifications:[2]
J1 – An athlete's vision impairment must result in a visual acuity of less than or equal to LogMAR 2.6 in binocular vision.
J2 – The athlete's visual acuity must be within a range between LogMAR 1.3 and 2.5 with binocular vision, or with a binocular visual field of 60 degrees or less in diameter.
