According to the World Health Organization’s first report on vision, more than one billion people worldwide are living with vision impairment because they do not get the required care for conditions like short and far sightedness, glaucoma and cataract. Launched ahead of World Sight Day on October 10, the report found that ageing populations, changing lifestyles and limited access to eye care, particularly in low and middle-income countries, are among the main drivers of the rising numbers of people living with vision impairment.
