OPTICAL LENS
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.

THE MANUFACTURING METHOD OF HIGH-REFRACTIVE POLARIZED LENS
Disclosed herein is a method for manufacturing a high-refractive polarized lens, the method comprises; pretreating both surfaces of the TAC film; preparing a pretreated polarized film by attaching the pretreated TAC film to both sides of a PVA film; forming the prepared pretreated polarized film into a lens shape; placing the formed pretreated polarized film on a mold for manufacturing a lens; injecting a polythiourethane-based resin into a lens manufacturing mold on which the pretreated polarized film is placed; and cooling the polythiourethane-based resin while the mold is fixed.
Method for producing contact lenses
The invention provides a method producing contact lenses, comprising the step of: separating the mold into the male and female mold halves, with the silicone hydrogel contact lens adhered on one of the male and female mold halves; cooling the lens-adhere mold half with the molded silicone hydrogel contact lens adhered thereon; bringing a shaped ultrasonic horn in direct contact with at least one area of a non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon; and applying a ultrasonic vibrational energy to the at least one area of the non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon so as to separate the molded silicone hydrogel contact lens from the mold half attached thereon.
