India previously classified a person as ‘legally blind’ if they were unable to see the number of fingers held up by a hand 6 metres away, rather than the 3 metre distance used by other countries
by dropping the 6 metre and adopting the more stringent 3 metre rule, the number of ‘legally blind’ in India has fallen by around 4 million and the country does not now compare so unfavourably with the rest of the world – http://tinyurl.com/mpeuam4
of course, India could reduce the number of legally blind in the country still further and . . .
