Abstract
An ophthalmic lens comprising a main lens part, a recessed part, an optical center, and an optical axis through the optical center. The main lens part has at least one boundary with the recessed part and has an optical power of between about −20 to about +35 diopter. The recessed part is positioned at a distance of less than 2 mm from the optical center and includes a near part having a relative diopter of about +1.0 to about +5.0 with respect to the optical power of the main lens part. The boundary or boundaries of the recessed lens part with the main lens part form a blending part or blending parts, are shaped to refract light away from the optical axis, and have a curvature resulting in a loss of light, within a circle with a diameter of 4 mm around the optical center, of less than about 15%.
