Glasses With Adjustable Prescription FARM HOME Health 25-2-31 This one pair of eyeglasses will fit 90 percent of prescriptions. The glasses have hollow fluid-filled lenses whose curvature can be altered by turning a knob mounted on one of the bows.
The big catch on the glasses is that they have unfashionably thick frames. The inventor, Joshua Silver, an Oxford University physics professor in England, says the biggest market for the glasses at this time is to third world countries where eye doctors and prescription lenses are hard to find. For example, the government of Ghana plans to order 100,000 pairs to take to remote areas of the country. At this time the glasses sell for about $15 apiece.
