British Inventor Josh Silver has developer a couplet ofeyeglasses that are instantly adjustable . They ’ve got a liquid state - filled theca in the middle — add more fluid to make the glasses stronger , puncture to weaken them .
The no - lens maker - required glasses rely on the rule that the fatter a lense is , the more sinewy it comes , so by pump in or take in out fluid , the glasses can be like a shot tailored to the right strength . They ’re so simple to align that practically anyone can do it . So far the only complaint with the ice is that they ’re kind of ginormous — which kind of goes with throw specification that operate on the coke - bottle glasses principle and have a fluid - fill tissue layer ride in the middle of the electron lens .
Silver is planning a trial in India that will distribute over 1 million of the glasses , which he hopes to have strapped to the heads over a billion of the world ’s misfortunate people — at a price of $ 1 per pair — by the poetic date of 2020 . fortuitously for him , elephantine glasses are ironically cool again , so he could probably launch a Get 1 , Give 10 style political platform fund completely by hipsters .
