Abstract:
A lens element intended to be worn in front of an eye of a person includes a prescription portion having a first refractive power based on a prescription for correcting an abnormal refraction of the eye of the person and a second refractive power different from the first refractive power. The lens element further includes a plurality of at least three optical elements, at least one optical element having an optical function of not focusing an image on the retina of the eye so as to slow down the progression of the abnormal refraction of the eye.
