Inventor hopes adjustable glasses will bring sight to 1 billion people

Inventor hopes adjustable glasses will bring sight to 1 billion people

A retired Oxford University professor of physics hopes to give glasses to a billion of the poorest people in the world by 2020.

The Guardian reports Prof Josh Silver"s adjustable glasses, which contain fluid-filled sacs attached to syringes.

Wearers can make the lenses thicker, and therefore stronger, until they are satisfied with their vision.

Prof Silver"s team plan a pilot scheme in India for one million pairs and are aiming to have 100 million pairs distributed in the next few years - ultimately reaching one billion.

The Indian trial is taking place with the help of businessman and humanitarian Mehmood Khan.

Prof Silver said new designs and cost-cutting measures are being devised.

He stated: "The truth is that there is, at the moment, no device that can be made for a dollar in volumes of 100 million. But I am entirely confident that we can do that."

Those fortunate enough to live in countries where they can purchase contact lenses can also find that daily disposable lenses, such as 1 day Acuvue ones, can be bought inexpensively.
