It has become imperative over the years for eye health to be among one of the highly prioritized public health problems along with other important health issues globally. As per the estimates by the World Health Organization (WHO), about 285 million people are visually impaired. It clearly states in its Global Action Plan (2014-19) that if refractive error services and cataract treatment are provided on priority basis, about two-thirds of the visually impaired population will recover good sight. More than 90 percent of visually impaired people live in developing countries, where the health sector is constrained by lack of affordable and accessible infrastructure and availability of comprehensive eye health services.
