Visual Impairment
"WHAT IS VISUAL IMPAIRMENT?"
A visual impairment is generally defined as an eyesight problem that cannot be corrected by wearing glasses or contact lenses or by surgery.
The terms partially sighted, low vision, legally blind, and totally blind are used in the educational context to describe students with visual impairments. They are defined as follows:
Visual impairment is the consequence of a functional loss of vision, rather than the eye disorder itself. Eye disorders which can lead to visual impairments can include retinal degeneration, albinism, cataracts, glaucoma, muscular problems that result in visual disturbances, corneal disorders, diabetic retinopathy, congenital disorders, and infection.
"HOW COMMON ARE VISUAL IMPAIRMENTS?"
The rate at which visual impairments occur in individuals under the age of 18 is 12.2 per 1,000. Severe visual impairments (legally or totally blind) occur at a rate of .06 per 1,000.
"WHAT ARE THE CHARACTERISTICS OF VISUAL IMPAIRMENTS?"
The effect of visual problems on a child's development depends on the severity, type of loss, age at which the condition appears, and overall functioning level of the child. Many children who have multiple disabilities may also have visual impairments resulting in motor, cognitive, and/or social developmental delays.
A young child with visual impairments has little reason to explore interesting objects in the environment and, thus, may miss opportunities to have experiences and to learn. This lack of exploration may continue until learning becomes motivating or until intervention begins.
Because the child cannot see parents or peers, he or she may be unable to imitate social behaviour or understand nonverbal cues. Visual handicaps can create obstacles to a growing child's independence.

The terms partially sighted, low vision, legally blind, and totally blind are used in the educational context to describe students with visual impairments. They are defined as follows:
- "Partially sighted" indicates some type of visual problem has resulted in a need for special education;
- "Low vision" generally refers to a severe visual impairment, not necessarily limited to distance vision. Low vision applies to all individuals with sight who are unable to read the newspaper at a normal viewing distance, even with the aid of eyeglasses or contact lenses. They use a combination of vision and other senses to learn, although they may require adaptations in lighting or the size of print, and, sometimes, Braille;
- "Legally blind" indicates that a person has less than 20/20 vision in the better eye or a very limited field of vision (20 degrees at its widest point); and
- Totally blind students learn via Braille or other non-visual media.
