A visual impairment can affect cognitive, emotional, neurological, and physical development. Visual impairment impairs reading speed and comprehension, and is often mistaken for a learning disability. Learning is accomplished through complex and interrelated processes, one of which is vision. As a result, visual impairments limit the range of experiences and kinds of information to which one is exposed. A reliance on visual cues in health and risk messages intensifies these effects with regard to health information. The millions of children and adults who are affected by visual impairments worldwide thus require specific consideration regarding how best to make health information accessible for them. The reliance on caretakers to address the health information needs of those living with visual impairments violates their privacy and threatens their emotional well-being. Technological and modality advances that rely on touchscreens that lack tactile or auditory cues marginalize a broad segment of society that is in need of gateways to overcome barriers to accommodating visual impairment. In designing strategic health and risk messages, consideration should be given to this scope of possible limitation and its implications for access to and processing of health and risk information. Health and risk message designers should understand both the realities of challenges to accessing information for the visually impaired and strategies for addressing these realities and the scope of the issue worldwide and across the lifespan.
