In third world countries, a new set of self-adjustable specs that can be focused by the person wearing them could revolutionise eye care.
Called Eyejusters and developed by a British company, the glasses can be adjusted by simply turning a dial on the frame, allowing wearers to simply twist the dial until they can see clearly, the Daily Mail reported.
AdvertisementIt makes use of a technology called a Slidelens, and works by sliding one lens over the other when the wearer turns the dial. This changes the lens prescription to give clear vision.
The technology has been refined from an idea originally developed in the 1920s.
"We're happy to agree that optometrists provide a better standard of care.
They check for eye disease and all sorts of things that we can't do," the paper quoted Owen Reading, co-founder of Eyejusters and head of business development, as saying.
"However, our glasses are particularly useful for parts of the developing world where there are very few optometrists so people are unable to get a pair of glasses prescribed," he stated.
The company have sold the glasses to NGOs and charities in Sudan, Uganda, Cameroon, Morocco, and India.
It is also selling their product as reading glasses that can be sold over the counter. They're on sale in the U.S for 40 dollars.
"A lot of people have different pairs of reading glasses for different tasks but these are just one pair of glasses that do it all," said Reading.
The company is hoping to get the glasses, which are assembled in Southampton, to an increasing number of people in the developing world through a campaign launching next week called 'Give and Get'.
