An elegant, inexpensive solution to a global problem: Adaptive Eyewear has created a pair of glasses that can be altered to adjust to almost any corrective settings. The glasses work by injecting or removing fluid from the lens, thus altering the focus. The glasses were invented by Dr. Joshua Silver, and the company mission is to fulfill the vision correction needs of underserved populations in the developing world.
