The starting fourth dimension paragraph of the press release:
Contact lenses right many people's eyesight but produce null to ameliorate the blurry vision of those suffering from age-related macular degeneration (AMD), the leading campaign of blindness with older adults inwards the western world. That's because only correcting the eye's focus cannot restore the key vision lost from a retina damaged past times AMD. Now a squad of researchers from the U.S.A. as well as Switzerland led past times University of California San Diego Professor Joseph Ford has created a slim, telescopic contact lens that tin flame switch betwixt normal as well as magnified vision. With refinements, the arrangement could offering AMD patients a relatively unobtrusive agency to heighten their vision. The squad reports its travel today inwards the Optical Society's (OSA) open-access journal Optics Express.

Images captured through the contact lens as well as mechanical model oculus are shown. c) Outdoor icon taken with model oculus alone. d) Outdoor icon taken with model oculus as well as contact lens. This icon shows why each of the 2 magnification states (normal as well as 2.8x) should last used 1 at a time: Here, neither department of the lens is beingness blocked past times the glasses, as well as the upshot is an icon with greatly reduced contrast. e) Outdoor icon taken with exactly the magnified outer percentage of the contact lens (2.8x).
