Students who are blind or visually impaired require adaptations to the environment, materials, and instruction. Each student will have his or her own unique visual needs based on the student's visual impairment as well as other disabilities. It is important to understand each student’s visual diagnosis and the implications concerning functional vision to make the appropriate adaptations to maximize the students use of vision and access the same assignments as their sighted peers.
Materials should be adapted only to the extent necessary for efficient learning. If regular materials can be used in conjunction with environment adaptations or low vision devices, such an approach is preferable to using specialized materials. - J.M. Stratton: JVIB, Jan 1990 (84) 3-5
