✦ Synopsis

The number of blind in the world is not known, but estimates have been made based on the differing definitions of blindness used by various authorities -a fact that complicates the analysis of available data. There are also possible sources of error, such as unreliable population figures and a frequent lack of data from rural areas. 'Blindness' has varying meanings and consequences from the medical, social and economic points of view: the term usually connotes a severe loss of vision resulting in visual disability, constituting a considerable handicap in the daily life of the community.
