Abstract
A lens for viewing the anterior chamber of the eye includes a contact lens having a contact lens surface and an anterior surface. The anterior surface has an optical axis that intersects the optical axis of the contact lens surface. First and second mirror surfaces are positioned to redirect light rays from the periphery of the anterior chamber and reflect them in a direction parallel or nearly parallel to the optical axis of the contact lens surface.
