Braille Institute's VisionSim app for iPhone and iPad allows users with healthy vision to experience the world through the eyes of someone with degenerative eye diseases. With nine different eye diseases simulated, including age-related macular degeneration, cataracts, and diabetic retinopathy, this app provides a unique insight into the visual impairments faced by millions of people.

In addition to the simulations, VisionSim offers detailed information about each eye disease, including visual phenomena, symptoms, causes, and treatments. The app also provides a direct link to Braille Institute's website and offers the option to contact them via email for further information.
