2.1. A person who has a visual deficiency that, after correction by means of ophthalmic lenses, excluding special optic systems and additions greater than 4 diopters, leaves each eye with a visual acuity equal to or less than 6/120 or with a continuous visual field of less than 10 °, including the central fixation point, measured horizontally or vertically, and that, in either cases, renders the person incapable of making functional use of the visual aids of the print magnification method of communication, is functionally blind.
Despite the foregoing, a person who has fluctuating vision, a defective field of vision or sensitivity to contrast, or a degenerative eye pathology is deemed to be functionally blind if that vision, defect or pathology renders the person incapable of making functional use of the visual aids of the print magnification method of communication.
