Abstract: The method and apparatus for marking of soft contact lenses with identification indicia is disclosed. A film cartridge is provided for supporting a non-gel film having lens marking indicia gel or dye disposed thereon. The cartridge has an opening therein to access the film and a backing pad is positioned proximate the film opposite the opening to disperse marking contact force. A lens supporting pedestal having a curvilinear head is provided for supporting the lens in a marking position. A pair of spring biased latches are provided for engaging either end of the cartridge which includes recesses to engage the latching members. A guide is provided for aligning the cartridge, and the film supported therein, with the curvilinear marking head. The cartridge and pedestal are sized to cause a predetermined force to be applied to the film against the backing pad through the lens to be marked. To mark a lens, it is cleaned, rinsed and dried, and positioned on the curvilinear head.
