Cheap specs for developing world

10th February 2009

A retired Oxford professor has invented a pair of eye glasses which could be used by people in poorer countries.

The glasses can be adjusted by the injection of small amounts of fluid to the lenses. Professor Joshua Silver is making preparations to give out the spectacles in India at a rate of one million pairs per year. His aim is to give out 100 million pairs a year, with one billion distributed by 2020.
