"Ever wondered how a visually impaired person sees the world? This app for Google Cardboard can simulate a number of visual impairments including: cataracts, macular degeneration, glaucoma, diabetic retinopathy, floaters, and 3 different types of colorblindness (deuteranopia, protanopia, tritonopia).
SimViz provides a better understanding of how individuals with visual impairments perceive the world around them and it enables interface designers to perform quick accessibility inspections during design. This app works with Google Cardboard or other smartphone VR adapters." - Via Eelke Folmer.
