Abstract: A lens element intended to be worn in front of an eye of a wearer includes a refraction area having a refractive power based on a prescription for said eye of the wearer. The lens element further includes a plurality of at least two contiguous optical elements, at least one optical element having an optical function of not focusing an image on the retina of the eye of the wearer so as to slow down the progression of the abnormal refraction of the eye.

Abstract: An optical device for capturing images of an eye of an individual, the optical device having a first measurement channel and a second measurement channel. The first measurement channel generates at least one first lighting beam directed toward the eye and along a first axis and to capture at least one first image of the eye when illuminated by the at least one first lighting beam. The second measurement channel is generates at least one second lighting beam directed toward the eye and along a second axis separated from the first axis by at least 5°, for example at least 10° or at least 20° and to capture at least one second image of the eye when illuminated by the at least one second lighting beam. The first measurement channel and the second measurement channel are synchronized together.

Abstract: An optical device for a wearer intended to form an electrochromic ophthalmic lens, spectacle glasses comprising two such lenses fitted on a frame, and a method for manufacturing such an optical device. The optical device includes at least one electrochromic cell which has a rear shell and a front shell respectively defining for the optical device a backside surface proximal to at least one eye of the wearer and an opposite front surface, the rear shell and the front shell being provided with at least one pair of transparent electrodes and delimiting a sealed cavity filled with an electrochromic composition. One of the front shell and the rear shell includes a mineral glass substrate, and the other one includes an organic polymeric substrate, and the electrochromic cell forms a hybrid mineral-organic ophthalmic lens selected from plano lenses and prescription lenses satisfying a prescription for power correction.
