| Abstract | A method for manufacturing a lens element intended to be worn in front of an eye of a wearer, the method comprising obtaining a lens member comprising a holographic recording medium disposed on a first surface of the lens member, the holographic recording medium being configured to be able to convert an interference pattern into a holographic optical element, obtaining wearer prescription data relating at least to the prescription of the wearer, manufacturing a second surface of the lens member based on the wearer prescription data, and recording a holographic optical element within the holographic recording medium so as to provide an additional optical power of opposite sign to the prescribed optical power so as to slow down the progression of the abnormal refraction of the eye. |
