Blindness

Blindness is a total or near total loss of vision resulting from a variety of physiological or neurological causes.

A person who is legally blind at best can view at a distance of 20 feet away an object viewable by a person with average vision at a distance of 200 feet away.

Some persons classified as legally blind may have extremely limited vision (light, color or shadow perception only), while others may have no sight at all.

Blindness and extreme visual impairments often make major basic life activities more difficult when the design of the environment assumes average sightedness.

  • The student may have a complete loss of vision or extremely limited vision
