The International Federation of Ageing (IFA) has just published a new report about the prevalence and the cost of ageing in the developed and developing world.
The opening sentence of the Executive Summary says it all:
Vision loss − 80 percent of which is preventable − is currently the leading cause of age-related disability.
Worldwide, 285 million people are visually impaired, including 39 million who are totally blind. In developing countries, 94 million older people suffer from moderate to severe visual impairment − twice as many as those who suffer from significant hearing impairment.
Where there is a phenomenal need there is a phenomenal amount of business potential. Dick Stroud
