Professor Joshua D. Silver is a UK physicist whose discoveries have included a new way to change the curvature of lenses, with significant application for the low-cost manufacture of corrective lenses and adjustable spectacles, especially in low-income countries. Silver began his academic career in the Department of Atomic and Laser Physics at the University of Oxford, ultimately leading a research group. Professor Silver is currently the chief executive of the Centre for Vision in the Developing World at the University of Oxford, working to research the scope of and potential solutions to the problems of refractive error and low vision in the developing world.
