(PhysOrg.com) -- Researchers from the University of Arizona have created a fluid-based opthalmic lens in which the amount of fluid can be constantly adjusted to provide customized eye correction. The lens may one day be incorporated ...
Nearly 150 years ago, the physicist James Maxwell proposed that a circular lens that is thickest at its center, and that gradually thins out at its edges, should exhibit some fascinating optical behavior. Namely, when light ...
