Adjustable Glasses
Material ID: 953
Description
These glasses contain lenses which can be self-adjusted by the wearer to their prescription, and were developed as a low-cost and accessible eye care solution for people in developing nations. The lens consists of two membranes, in between which silicon oil can be pumped with the syringes on the side of the frames. As fluid is pumped in or out, the focal length of the lens is changed, meaning the lens can be tuned to the specific requirements of the eye. The syringes can then be removed. The inventor of these glasses was nominated for a 2011 European Invention Award.
