ABSTRACT OF THE DISCLOSURE The specification describes an apparatus for manufacturing a contact lens from a lens blank, the machine comprising a lens blank support rotatable about an axis, a first material removal tool mounted on a radius arm and arranged to traverse the support in an arc about an axis to form a first curved lens surface on a blank held by the support and a second material removal tool arranged to be movable radially of the support into engagement with the blank so as to machine a generally frusto-conical peripheral surface defining with the first curved surface a peripheral portion of substantially uniform circumferential thickness, the support and the tools being arranged so that the machining movements of both tools may be effected without removing the blank from the support.
