The rate at which visual impairments occur in individuals under the age of 18 is 12.2 per 1,000. 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. 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 behavior or understand nonverbal cues.
Visual handicaps can create obstacles to a growing child's independence.
Technology in the form of computers and low-vision optical and video aids enable many partially sighted, low vision and blind children to participate in regular class activities. Large print materials, books on tape, and braille books are available. Students with low vision or those who are legally blind may need help in using their residual vision more efficiently and in working with special aids and materials. Students who have visual impairments combined with other types of disabilities have a greater need for an interdisciplinary approach and may require greater emphasis on self care and daily living skills.
