摘要： Implementations described and claimed herein provide a complex surface of a progressive multifocal ophthalmic lens. In one implementation, the complex surface includes: a difference in ratio between cylinder value and surface addition less than 0.2 in absolute value; a first ratio between a maximum cylinder value for all points in a grouping circle and a surface addition; and a second ratio between a maximum cylinder value for all points on a disc and a surface addition. In another implementation, the complex surface includes: a difference in ratio between resultant astigmatism value and prescribed addition less than 0.3 in absolute value; a first ratio between a value of resultant astigmatism for all directions of gaze passing through an angular circle and a surface addition; and a second ration between a value of resultant astigmatism for all directions of gaze passing inside the angular circle and a prescribed addition.
