In microsiervos I found this article that I find very interesting and encouraging for everyone, something for which we have things nearly always seems almost unthinkable, but it is reality. (Administrator gacetanews)
The idea of adaptive lenses, developed by Professor Josh
Silver, now retired from the University of Oxford, is
develop glasses that everyone can fit their needs correction by itself, without further reference to an optician in the process.
It is estimated that roughly half the world population needs
some form of sight correction and millions of people lack access
no possibility of going to the eye doctor, let alone buy a pair of
glasses.
Silver glasses that are based on the thicker the lens,
greater its ability corrective. Between the rigidlenses
is a flexible plastic membrane that can landings with more or less
amount of clear fluid. The user of the glasses can graduate
the amount of fluid that enters the lens. When it finds the
appropriate adjustment shuts off fluid tightening a screw.
A simple process which investigators said anyone can do with a minimum indications.
Currently 30,000 people are already using glasses
Silver in fifteen countries. Few even as the physical, that
2009 is intended to distribute one million glasses in India.
The aim is to improve the current design, reducing the price of these
sunglasses to a dollar a unit and by 2020 he has given one billion
pairs among the poorest.
