Abstract
Disclosed herein is a lens comprising a central portion that comprises a first polymer; wherein the central portion is operative to transmit electromagnetic radiation through it; and a peripheral portion that comprises a second polymer; where the peripheral portion accommodates a dimensional change in the central portion by absorbing energy and being transformed from a lower energy state to a higher energy state. Disclosed herein too is a method of manufacturing a lens comprising injecting into a mold a molten polymer to produce the lens; where the lens comprises a central portion; and a peripheral portion; where the peripheral portion accommodates a dimensional change in the central portion by absorbing energy and being transformed from a lower energy state to a higher energy state.
