The present invention provides improved ophthalmic lenses and methods fortheir design and use. Monofocal andmultifocal diffractive ophthalmic lenses having reduced light scatter,improved light energy distribution properties, and/or otherimprovements in optical performance are provided. These properties areprovided, at least in part, by the diffractive profiles of theinvention, often having subtlety shaped echelettes with appropriately curvingprofiles. Smooth diffractive profiles may be used reducelight scatter. Diffractive profiles may be configured to limit the lightenergy in certain selected orders, thereby improvingviewing quality and mitigating unwanted effects such as dysphotopsia.Diffractive profiles of may additionally or alternativelyvary the light energy distributed between individual echelettes, providingadditional advantages in various viewing situations.
