Professor Joshua Silver, who designed the unique self adjusting eye glasses expressed the hope that at least a billion people will be able to get spectacles in few years.
Silver is planning to launch a scheme to distribute these eye glasses in India and has fixed the target at one million.
These glasses can be tuned by the wearer and that too without any prescription. They will be useful for both short-sighted as well as long-sighted people.
It took 20 years of hard work and research for Silver to finally arrive at a design, which could be produced on a large scale. His spectacles uses thicker lenses and fluid is injected in them to make workable for all kinds of users.
The spectacles comprise plastic glasses and liquid in the lenses, which can be added or removed with the help of syringes controlled by a dial. Silver feels that these spectacles could end the wait for millions of people, who can not afford costly prescriptions and expensive eye glasses.
