A method of manufacturing a contact lens with an iris simulating pattern by moulding comprising applying to the mould at least two differing designs so as to form an overall pattern. This overall pattern is transferred to the surface or surfaces of the contact lens during moulding and curing thereof, where the designs transferred interact with each other to substantially cover the iris and produce a coloured natural simulation of the iris of the eye when in use. <IMAGE>
