(57) Abstract: A method of providing a patient with a contact lens, according to which an optical preform (20) is selected and the resting position of the optical preform is determined by the eyes of the patient. An optical feature (11) is also positioned on the patient's eye. Next, if the optical preform is in the rest position, the reference position is positioned on the surface of the optical preform that matches the optical features of the patient's eye. Finally, by machining the preform itself, or by subsequently machining the mold used to form the lens, the optical improvement is made at a position based on the reference position of the preform.
