Silver Glasses: liquid-injected lenses for a billion of the world's poor
We revere Santa Claus as our mysterious giver of gifts, but the rest of the world may reserve that spot for Josh Silver. Professor Joshua Silver, to be specific — a retired physics teacher at Oxford University who has developed "Silver Glasses," which are tunable spectacles that need no optometrist to adjust. That's because the glasses have syringes filled with silicone liquid connected to each lens, and the wearer only has to inject or suck out the fluid until the view through the lenses looks right.
Voilà! No optometrist fees, and the glasses are cheap and rugged. It's a bit reminiscent of the One Laptop Per Child (OLPC) program, which brought bare-bones laptops to impoverished nations. 10,000 Silver Glasses have already been delivered to Ghana on a trial basis, and Silver and co. hope to send out one million pairs a year, with the hope of having one billion of the spectacles on heads around the world by 2020.

My apologies to Dr. Silver -- from early patents (such as the one linked to below), it appears that his work pre-dated that of Mr. Griffith.

These glasses seem wonderful: I wish they were for purchase in the USA. Glasses are too expensive. Many people wear the wrong prescription, and or broken glasses, for many years.

It would be great if Dr. Silver could make these glasses available for those in first world counties too. I'm sure many people would buy them and the revenue would surely help fund his aid efforts for the third world countries.

I help a very worthy organization that could use some of those billion glasses. I am also an optician and am very interested in this concept.
Please contact me so I can discuss the organization that I would like to see get some of these glasses.
Thank you,
lamamama

Great idea! I am near-sighted, and have always noticed if my eyes water I can see better. I missed a great invention opportunity! Please, Dr. Silver, Make them available to us in first world also!
