Visual

Blindness implies a total or near-total loss of the ability to visually perceive form. A visual acuity of 20/200 is considered legally blind in Canada, meaning that one can see at 20 feet what a person with good vision can see at 200.

Visual impairment is a generic term applied for students whose visual acuity is not sufficient for participating with ease in everyday activities. Visual impairment covers a range of difficulties with vision including, but not limited to:

• A visual acuity of 6/21 (20/70) or less in the better eye after correction
• A visual field of 20 degrees or less
• A progressive eye disease with a prognosis of becoming one of the above in the next few years
• A visual problem or related visual stamina that is not correctable and that results in the student functioning as if his or her visual acuity is limited to 6/21 (20/70) or less.
