Abstract
Abstract An optical lens having a transparent lens body for a human eye or mammalian eye is shown. The transparent lens body has an anterior surface and a posterior surface and has formed in the central area thereof at least one stenopaeic opening which is substantially perpendicular to the anterior surface and posterior surface of the lens body. The at least one stenopaeic opening has a dimension "d" which is selected to be a geometrical dimension such that an image of an object located in front of the lens, when the lens is implanted in, or placed upon, the eye, is projected through the lens generally along a predetermined light transmitting path defining the visual axis of an eye and onto the fovea centralis of the eye which is located in back of the lens. The optical lens containing the at least one stenopaeic opening selectively intercepts and passes light through the lens body along the visual axis onto the fovea centralis in a manner to obtain an optical effect by increasing the depth of focus of the eye in order to substitute for the loss of at least one of the focusing power and the accommodation of the eye. Also disclosed herein is an optical lens having at least one stenopaeic opening located substantially central or paracentral therein and having a plurality of stenopaeic openings spaced from and positioned around the at least one stenopaeic opening wherein each one of the plurality of stenopaeic openings has a selected dimension "d".
