The British inventor Josh Silver,professor of physics at the University of Oxford, has developed this new idea of glasses characterized by slow water.
Silver developed the idea that a lens, is more thickened, becomes more powerful. The main concept is a structure formed by two plastic membranes, that act as lenses, which are filled with a fluid. These lenses are connected to the eyeglass temples within which there is a system of regulation of the flow of fluids.
Who wears these glasses can handle the influx of fluid into the lens, allowing it to increase strength; once it reaches the optimum viewing the flow of fluid is blocked by a screw.
You can set up mass production for these lenses, which surely are not going to developed countries' economic prinicipi, but they are a great solution for those developing countries, where the visual deficiency is a further problem also economic.
