摘要:
A lens element adapted for a person including a holder including a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of the person, a plurality of optical elements placed on at least one surface of the holder to at least one of: slow down, retard, or prevent a progress of the abnormal refraction of an 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 element and at least a zone of the holder on which the optical elements are placed, wherein said at least one layer of at least one coating element adds an optical power of 0.1 diopter in absolute value in specific wearing conditions when measured over said zone of the optical element covered by said at least one layer of at least one coating element.
