Abstract

A lens element to be worn by a wearer and to provide a refractive power based on a prescription of the wearer is provided for correcting an abnormal refraction of the eye of the wearer, the lens element including: an optical microstructure having an optical function of not focusing an image on a retina of the eye of the wearer so as to slow down progression of the abnormal refraction of the eye of the wearer, in which a modulation transfer function of the lens element is greater or equal to 0.07 over a range of spatial frequencies from 10 to 25 cycles per degree, when measured through the optical microstructure for a pupil aperture of 4 mm centered at 6.6 mm from the optical center of the lens element. A computer-implemented method for determining a lens element to be worn by a wearer is also provided.
