Abstract

The invention tackles the problem of improving the production process for contact lenses further, so that the production costs for contact lenses can be reduced further and the production capacities can be increased. To this end, provision is made for the two mould halves, which together form the mould for producing a contact lens, to be fixed to each other and/or detachably connected to each other by means of individual half-mould guide. In conjunction with a cyclic production process, a high degree of automation can be achieved in this way.
