Defining Cortical Visual Impairment (CVI)
CVI is a brain-based visual impairment in which the eyes may be healthy, but the brain cannot reliably interpret visual information. It is currently the most common cause of visual impairment in children in the United States. Students with CVI often show fluctuating visual attention, difficulty recognizing objects or faces, and variable use of vision across settings.
CVI at School
Students with CVI generally need learning environments that reduce visual clutter, present information with clear contrast, and limit competing sensory input. They often require adapted materials with simplified layouts, predictable visual routines, and strategic use of color to highlight key information. Many benefit from explicit teaching of visual concepts, tactile and auditory supports to supplement vision, careful positioning to optimize visual fields, and additional processing time. A Certified Teacher of Students with Visual Impairments (TVI) can help design CVI-informed accommodations, select appropriate materials, and guide teams in making instruction accessible.
