Abstract
An apparatus for tinting a soft contact lens which is received in a fixture including an inlet and an outlet for directing predetermined fluids therethrough for engagement with predetermined surfaces of the contact lens. The apparatus comprises a carrier for carrying the fixture in a predetermined orientation; a guide arrangement for defining a predetermined path of travel; a motive assembly for propelling the carrier along the predetermined path; and a plurality of fluid application stations arranged along the path, each fluid application station including a fluid release member. The guide track and the motive assembly cooperate for aligning the inlet of the fixture with each fluid release member sequentially as the carrier travels along the predetermined path, for delivering a quantity of fluid to the fixture and the contact lens therein. A method for tinting soft contact lenses comprises the steps of mounting a contact lens to a fixture including an inlet and an outlet for directing predetermined fluids therethrough for engagement with predetermined surfaces of the contact lens; mounting the fixture to a carrier in a predetermined orientation; guiding the carrier along a predetermined path of travel; arranging a plurality of fluid application stations along the predetermined path, each fluid application station including a fluid release member; and further moving the carrier as it moves along said path in a direction for aligning the inlet of the fixture with each of the fluid release members, sequentially for delivering a quantity of fluid to the inlet.
