A process for the automatic manufacturing of different toric optical lenses having a front surface and a rear surface having a predetermined rotational orientation relative to one another, and with at least one of the front and rear surfaces having a toric portion, comprises forming a first toric lens by: introducing a starting material into a lens mold (3) comprising a male mold half (30) and a female mold half (31) defining a mold cavity between the shaping surfaces of the male and female mold halves, the shaping surfaces being arranged at a first rotational position relative to one another and at least one of them being toric, and curing the starting material in the mold cavity to form the first toric lens. The process further comprises subsequently forming a second toric lens different from the first toric contact lens using the same male and female mold halves (30,31) by rotating the first and second mold halves (30,31) relative to one another so as to be arranged at a second rotational position relative to one another, and then forming the second lens in a similar manner. The step of rotating the male and female mold halves (30,31) relative to one another is performed automatically in the production line.
