Abstract
A method of correcting vision defects associated with central field loss. The method is effected by passing light arriving at a retina of an eye through an image deflection ophthalmic optical element including a lens body, the lens body including a lens portion for focusing light entering the eye and a prismatic holographic element being in context with the lens portion, the prismatic holographic element being for deflecting the light entering the eye to off a center of the retina.
Claims19
An interocular image deflection ophthalmic optical element adapted to be in intimate contact with an eye of a patient suffering macular degeneration and having a retina, the ophthalmic optical element comprising a lens body including a lens portion for focusing all visible light entering the eye and a prismatic holographic element being in context with said lens portion, said prismatic holographic element being for deflecting said light entering the eye off a center of the retina, so as to deflect an entire scene off said center of the retina and improve eyesight in cases of macular degeneration.
