Abstract
An artificial lens including a lens system having eccentric axes for in an eye having a macula and an enlarged natural pupil is shown. The artificial lens comprises a first optical lens system and a second optical lens system. The principal axis of each optical lens system is eccentric to each other and the distance between each principal axis is selected to enable the first optical lens system and the second optical lens system to be operable within the enlarged pupil. The lens system of the artificial lens system directs light rays from each image of each lens of the first optical lens system and second optical lens system onto a fovea centralis of the macula of an eye. In the preferred embodiment, a prism having a preselected diopter power is positioned on a selected surface of one of the first optical lens system and second optical lens system for directing light rays from an object onto a fovea centralis of the macula of an eye. A contact lens having an eccentric optical system is also shown.
