Virtual and Augmented Reality Device Simulates Vision Loss

Researchers have demonstrated how commercially available head-mounted displays (HMDs) can be used to simulate the day-to-day challenges faced by people with glaucoma. Glaucoma is an umbrella term for a group of degenerative eye diseases that affects the optic nerve at the back of the eye. It is the leading cause of irreversible blindness worldwide. Potential applications of the technology could include helping policymakers better assess the impact of visual impairment on patients and helping architects to design more accessible buildings.
