Eye screening and/or preventive behaviour has not been a priority among disadvantaged due to their socio-economic status which has reduced their lives to an eternal struggle for survival. Many of them may not be able to distinguish vision problems because they think that the way they see is the way everyone sees.
According to the estimates of World Health Organization (WHO), globally 2.2 billion people have vision impairment or blindness, of which over 1 billion cases could have been prevented or are yet to be addressed. India has the highest level of blindness in the world.
Low-income population specifically socially & economically disadvantaged elderly women and men are either unaware of their eye and vision deficiencies or unable to find affordable and reachable points of eye care services. Also, inadequate motivation to get it treated and cured compel them to live, and die, with curable blindness.
