Sight is our dominant sensory input. In a global YouGov survey commissioned by the World Innovation Summit for Health (WISH) in 2018, 74 percent of respondents identified sight as the most precious of the five senses. Our vision dramatically affects our awareness and perception of the world around us. Lost or impaired vision has an enormous impact on quality of life and economic productivity, as well as potentially reducing life span due to lifestyle and related health factors.1,2 In 2015, 36 million people worldwide were blind, and 217 million people had moderate to severe visual impairment (MSVI). Yet the World Health Organization (WHO) estimates that more than 80 percent of global visual impairment is avoidable or curable.
