Abstract
An ophthalmic multifocal lens providing far, intermediate, and near vision having a light transmissive body with an optical axis and a refractive baseline extending over part of the lens body; further having a first portion coinciding with a central area of the lens body and a multifocal second portion extending concentrically radially; the second portion further comprising a symmetric multifocal diffractive grating superpositioned onto the baseline, covering a portion of the lens, its shape and resulting light intensity distribution changing with distance to optical axis, the first portion being substantially concave, connected to the ridge of the grating that is closest to the optical axis and provides a dominant optical power between intended far and intermediate powers; configured to have an energy ratio intended for far vision to energy intended for near vision being lower for predetermined aperture(s).
