description	@ A contact lens is manufactured by a method involving machining a first face (2, 3) and a reference surface (4) on a blank (1); mounting the blank (1) in a work holder (10) adapted for accurate mounting on a lathe such that the blank (1) is held with its first face (2, 3) accurately positioned relative to a datum point on the lathe; and machining a second face (8) on the blank (1). Such method avoids the need for skilled operatives and enables easy manufacture of accurately dimensioned contact lenses.
