Challenges of Visual Impaiments
Visual loss imposes three basic limitations on children. These limitations include the range and variety of experiences, the ability to get about and the limitations in the ability to control the environment and oneself.
Special provisions to this group of children must take into consideration all implications of perceptual restrictions which go far beyond adaptation of tool subjects.
The main importance of the sense of hearing to a child with blindness is to facilitate verbal communication and aid in movement. Hearing therefore is of very limited value in acquisition of concrete clues of an object for a blind child.
The blind child who hears the twitter of a bird may know with more or less accuracy from where the bird sound comes from, but all his listening will not give him any idea of the shape of the bird’s body, or of his size or its physical characteristics, It becomes very challenging for a learner who is blind to perceive spatial qualities of objects without being provided with materials in form of models or embossed diagrams for touch and manipulation in which kinesthetic sensation participates.
