Perception & utilization of a Smartphone Magnifier App by Visually-Impaired Seniors

Mobile applications (apps) have become increasingly important for everyday life and can offer additional accessibility for patients with visual impairment. We sought to determine whether and how older adults with low vision would utilize a free mobile application (app) that provides electronic magnification, as well as gauge their preferences for the magnifier app compared to other types of visual aids. Visually-impaired seniors used the SuperVision+ app on a loaner iPhone for a 3-month period. App ratings and usage were self reported by subjects in a phone survey administered by investigators. The magnification app was preferred and rated as excellent or good by most visually-impaired seniors who compared it to their smartphone camera. Targeted interventions may be needed to support the use of magnifier apps outside the home by older seniors.
