    Abstract: The invention relates to a method for absolute measurement of the geometrical or optical structure of an optical component (4), comprising steps consisting in: - illuminating the said optical component with incident light, the wavefront of which is known, - measuring, in a given plane, the maps of the slopes of the wavefront of the said light after reflection from the said optical component or transmission by the said optical component, which furthermore comprises at least one calculation procedure consisting in deducing the geometrical or optical structure of the optical component from the said measurement of the slope maps. A further subject of the invention is a device for implementing this method. The invention is applied in particular in the field of ophthalmology for checking or measuring ophthalmic lenses or moulds for fabricating ophthalmic lenses.

    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.
