Disclosed is a method for manufacturing a lens element intended to be worn in front of an eye of a person, the lens element including two opposite optical faces and a plurality of optical elements each having an optical function of not focusing an image on the retina of the eye of the person so as to slow down the progression of the abnormal refraction of the eye. The method includes: providing a lens blank having at least one unfinished face; and processing the at least one unfinished face to obtain in combination with the opposed optical face a refractive power based on the prescription for the eye of the person and at least a part of the plurality of the optical elements.
