Students learn through the use of braille or related media without the use of vision.
Students with low vision learn from vision and other senses. Functional vision will depend on factors such as lighting, use of optical aids and devices, tasks, and personal characteristics. Modifications in lighting, size of print or objects, and distance may be required. The degree to which visual impairments affect development depends on the type of visual loss, severity, age of onset, intellectual ability, and environmental experiences. The lack of vision or reduced vision may result in delays or limitations in motor, cognitive, and social development.
