A method of removing a contact lens from a lens mold portion carrying a contact lens, the method comprising reciprocally displacing a region of the mold portion to thereby cause an edge portion of the contact lens to become detached from the mold portion, wherein the reciprocal displacement comprises a plurality of cycles, each cycle comprising motion in a first direction, followed by motion in a second, opposite direction.
An apparatus for removing a contact lens from a lens mold portion, the apparatus comprising:
- a platform for retaining the lens mold portion;
- and
- a reciprocating member arranged to reciprocally displace a region of said lens mold portion when the lens mold portion is retained by the platform, wherein the reciprocal displacement comprises a plurality of cycles, each cycle comprising motion in a first direction, followed by motion in a second, opposite direction.
