Claim:
A process for manufacturing an ophthalmic lens, comprising the steps of providing a mold assembly comprising a first mold half having a first molding surface and a second mold half having a second molding surface in an open position; dosing a lens forming material into the first mold half; closing the first and second mold halves to form a mold cavity defining the shape of the ophthalmic lens; curing the lens forming material in the mold cavity; opening the first and a second mold halves; removing the lens from the first or second mold half; and wherein (i) the step of closing the first and second mold halves comprises moving the first and second mold halves to an intermediate closed position, wherein the first and second molding surfaces of the first and second mold halves are arranged at an intermediate distance increase (d 1 ) relative to a final distance (d 0 ) in a final closed position; and (ii) during curing of the lens forming material moving the mold halves to the final closed position, wherein the intermediate distance increase (d 1 ) is 0; and then re-opening the mold halves to the intermediate closed position wherein the first and second molding surfaces of the first and second mold halves are arranged at a distance increase (d 1 ) relative to the final distance (d 0 ) in the final closed position.
