RT Journal Article SR Electronic T1 Sex, gender and blindness: a new framework for equity JF BMJ Open Ophthalmology FD BMJ Publishing Group Ltd SP e000135 DO 10.1136/bmjophth-2017-000135 VO 3 IS 1 A1 Lesley Doyal A1 Raja G Das-Bhaumik YR 2018 UL http://bmjophth.bmj.com/content/3/1/e000135.abstract AB Four-fifths of all blind or vision impaired people live in middle-income and low-income countries with the African region and parts of Asia and the Middle East bearing the heaviest burden. At the same time, we know that around two thirds of all blind people in the world are female. Hence, the poorest (and usually the oldest) women are most likely to have their lives limited by visual impairment. While recent strategies have focussed on international variations in eye health, very few have paid attention to the gender differences that are an inextricable element in these inequalities. This review will explore possible explanations for the advantage of men in the exercise of one of the most basic of human senses. It will show that this cannot be understood through the use of a biomedical approach alone. Broader social perspectives will also be needed in order to create an appropriate knowledge base for tackling global inequalities in blindness.
