ABSTRACT:
The contact lens system includes a large contact lens worn on the eye and a hard contact lens worn over the soft contact. One of the lenses is transparent. The other lens has an opaque area to prevent light from entering the eye except at a circular transparent area, to provide a piggyback light occluding lens system.
