Caption: These light-gathering polymer lenses are 3.5 times more powerful than glass, and are the first commercial nanolayered product to come out of many years of R&D at Case Western Reserve University. To create the lenses, a 4,000-layer film is coextruded, and then 200 layers of film are stacked to create an 800,000-nanolayer sheet.
