An aspheric ophthalmic lens design method that has both refractive power and diffractive power that can reduce eye chromatic aberration and at least one monochromatic aberration combines the aspheric refractive and diffractive surfaces to select the appropriate eye model. Establishing a design lens having at least one aspheric surface capable of reducing monochromatic aberrations in the eye model, establishing a diffractive lens element that corrects the chromatic aberration of the eye model, adjusting the lens surface design, Get a suitable high multicolor image quality in a weighted form to meet the merit function. |
