Abstract
A transparent optical component having cells (1) filled with an optical material is proposed, which has a high transparency. The cells of the component are filled to levels (h1, . . . , h5) which vary randomly, and the variations of which are adapted so as not to cause a perceptible optical defect. To do this, the fill levels of the cells are adapted so that the phase shifts experienced by the light rays (R1, . . . , R5) which pass through the cells have a root mean square deviation of less than one quarter of the wavelength (1). Such a component may in particular be an ophthalmic lens.
