Abstract
Apparatus and methods are described including an additional lens () made from an amorphous viscoelastic material and having an optical design. A curvature of the additional lens () is changed such as to conform with a curvature of abase eyeglasses lens (), without causing a loss of the optical design of the additional lens (), by heating the additional lens () to a temperature at which a Tan Delta of the amorphous viscoelastic material is between 0.2 and 0.8, and shaping the additional lens (). Subsequently, the additional lens () is adhered to the base eyeglasses lens (). The optical design of the additional lens () is such that, upon being adhered to the base eyeglasses lens (), the adhered base eyeglasses lens () and the additional lens () provide a combined lens () having a desired optical prescription. Other applications are also described.
