Liquid Glasses

A new kind of glasses may solve a major world problem

What would you do if you had trouble reading this page? You would probably go to an eye doctor who might give you glasses. For many people around the world, though, such a solution isn't that simple. The World Health Organization reports that around 1 billion people in the world could benefit from glasses. Yet places like Ghana have only one optometrist per 8 million people. This makes glasses almost impossible to get. Joshua Silver, a professor at Oxford University, however, may have solved the problem.

Silver has developed liquid-filled glasses that wearers adjust themselves without seeing a doctor! The lenses are filled with oil. Using a dial on the glasses, the wearer adjusts the amount of oil. This changes the strength of the lens. After the wearer finds the right strength, he seals the lens with a valve. Results show that among those who have tried the glasses, around 80 percent successfully corrected their vision. Silver's goal is for everyone who still needs glasses to have them by 2020. With his self-adjusting glasses, Silver may find that his goal just might be in sight.

Kevin White began Global Vision 2020 as a way to distribute Silvers glasses to needy people around the world. He trains volunteers from local organizations in developing countries. The volunteers are given two simple tasks: distribute glasses to those in need and train OTHER local volunteers to do the same. In this way, White says the Global Vision vision will continue to grow!
