They were indeed for use in underdeveloped countries. The lens power was adjustable by the user or a breifly trained technician to correct for small to moderate amounts of hyperopia (farsightedness) or myopia (nearsightedness). The lenses were made from a stiff membrane on one side, a more flexible membrane on the other and oil in between. A syringe type device "injected" the right amount of oil to create a plus or minus power lens. It is still in development. The lens mentioned in the article by Phillips could have broader usage than spectacle lenses. Interesting technology. On the other hand, it may be a "cure" looking for a "disease."
