When vision is impaired, learning can be significantly affected. Visual impairments may be present at birth or develop from illness or injury. There is a distinction between blindness and visual impairments.
Blindness is the total loss of light perception.
A visual impairment is a deviation from normal eye functions that may result in partial or total loss of sight, may be temporary or permanent, reversible or progressive. Significant visual impairment even with best correction, resulting in limited or diminished vision. Speak to the visually impaired person, not through a third party or companion. If possible, make available a list of reading assignments 3 to 5 weeks before class begins for document conversion. Have materials available in alternative formats at the same time materials are given to other class members.
