Around the world, organisations of many kinds are joining forces to help protect the eyesight of older people, and to mark World Sight Day 2008 (WSD08).
Worldwide, 45 million people are blind, the great majority of whom are over 50 years of age, but in over three-quarters of cases, especially those affecting older people, the sight loss results from preventable or treatable causes (otherwise known as avoidable) - 75% of blindness is avoidable.
