According to foreign media reports, Oxford University scientists develop DIY adjustable glasses, without professional equipment can be their own spectacles, the world's one billion poor people would benefit.
20 years ago, a professor of physics at Oxford University has long been envisaged to create this DIY adjustable glasses, now this idea has been realized. It is reported that currently there are 30 000 such glasses assigned to 15 countries, he thought 2020 would be the world's one billion poorest people to provide such glasses. Moreover, the already retired professor and his research team plans to conduct eye exams next year in India, plans to release a one million glasses. They target the next few years is to release 100 million glasses each year. After careful study they estimated more than half of the world's population need basic vision correction, so they have no reason to stay, Professor Sylvie 10 million people in the target.
According to reports, this spectacle lenses are two flat circular transparent plastic bag, which is empty, you can complete the syringe filling liquid to the plastic bag, syringes, there is scale, according to the different degrees of myopia, injection The corresponding volume of liquid extract or to change the role of plastic bag. Well, after the adjustment, you can use a small screw this plastic bag sealed, you can remove the syringe. The basic principle of this spectacle is the more flat plastic bag the greater its effect. And its operation is simple, the team found that people simply can guide people to good places to build their own prescription glasses.
This invention won the hearts of the main reasons for training in developing countries is difficult enough optometrists, there are currently 4,500 people each, a British optometrists, and sub-Saharan Africa is 1 million people own an optometrist, the gap is quite big. Therefore, the scientists said this showed that the needs of the poor communities of the great spectacles. Also, wearing the right glasses bring them many benefits. For example, fishermen had good visual acuity after repair to their nets, and after a woman can weave a good vision. In early field tests, Sylvie met a man named Henry, his vision for older and weaker, and no longer see clear line through the sewing machine needle, had to retire. However, when he retired about 35 years old, he can work at least 20 years. Sylvie their ration of such glasses he was, he was pleased to laugh. Because he can thread the needle and can work. There are many such people as Henry are very satisfied after wearing glasses.
Of course, the payment of 100 million glasses is not easy, if not profitably increase glasses per USD 1, that is 100 million U.S. dollars in huge amounts of money. In India, Khan Sylvie and businessmen together, as Khan did a charity, in Haryana village a little north of 500, the promotion of such glasses more convenient. In addition, Sylvie also face enormous challenges in the manufacture and distribution of tasks. Moreover, he also faces complaints of public opinion, said the size and design of this glasses are a poor bunch. In this regard, Silvey said they are doing some design and ready to further reduce prices. He said: "I fully believe we can do." This is his decision, you do not oppose.
Encouraged by his University of Oxford agreed to let him use the visual centers in developing countries, where to begin by the World Bank-funded projects, the project scientists from the United States, China, Hong Kong and South Africa. He said: "Things are never simple, but I hope I can solve this problem."
