Optical lens

A method implemented by computer means for determining a lens element, the lens element comprising:

• a holder comprising a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of an eye of the person;
• a plurality of optical elements placed on at least one surface of the holder so as to at least one of slow down, retard or prevent a progress of the abnormal refraction of the eye of the person;
• and
• at least one layer of at least one coating element covering at least a zone of at least one optical elements and at least a zone of the holder on which the optical elements are placed,
• wherein the method comprises:
• providing lens data, the lens data indicating at least a shape of the lens element to be determined, the shape of the lens element corresponding to a shape of the holder and to at least a shape of the optical elements of the lens element, the shape of the optical elements being associated with a targeted optical function;
• providing a coating lens transfer law associated with a coating process of a lens element comprising the optical elements, the coating process being associated with the coating element, the coating lens transfer law corresponding to transformations to apply to the shape of the surface of the lens element comprising
• the optical elements for compensating modifications of the targeted optical function of said optical elements induced by the coating process;
• and
• determining the lens element based at least on the lens data and the coating lens transfer law.
