ABSTRACT:
An ophthalmic lens having two elements, a contact lens and an entry lens. The lens produces a magnified aerial image of the fundus of the eye, and can also be used for laser delivery to the fundus. The lens is particularly useful because it provides high magnification and detail of the fundus as well as excellent steroscopic field.
