Visual Impairment Overview

An impairment in vision that, even with correction, adversely affects a child's educational performance, including both sight and blindness.

Low vision students use vision as their primary sensory channel, while totally blind students rely on tactile and auditory channels for learning.

Congenital visual impairment occurs during fetal development, at birth, or immediately following birth, and is present before visual memory is established.
