Professor Joshua Silver , the humanity who first woolgather the Methedrine up 20 old age ago when he was a physical science professor at Oxford University , England , was shortlist for a 2011 European inventor award last week . He hop to make a billion span of glass , but he ’s still struggling to reach that £ 1 - a - pair ( $ 1.60 ) fabrication cost . presently , they cost about £ 15 ( $ 24 ) a duo to manufacture , but as Silver says “ we have to get that cost down if we need to get these in numbers to children in Africa or Asia . ”
If successful , the person just has to look at an eyechart and manually adjust the glasses themselves , which work by filling the two adaptive lenses with more or less silicone polymer gel . The more gel that ’s pump between the two thin lenses , the hard the prescription medicine . Another issue Silver is facing is one of aesthetics — namely , they ’re not the coolest systema skeletale on the block . “ If we want teenagers to have on them , we will have to make them less obtrusive and more fashionable . In pith , we want to make them look just like standard glasses , ” Silver commented . [ The Guardian ]
