ABSTRACT:
A contact lens for use with pupil monitoring systems. A contact lens has a first surface that conforms to a cornea and sclera of patient's eye, and a second surface that has a tubular extension defining a viewing port formed thereon. A distal region of the tubular extension forms an outwardly protruding lip which functions to securely engage the eyelid of a patient during the monitoring process and facilitates manipulation of the scleral contact lens while it is being inserted in or removed from a patient's eye. The lens may conform solely to the cornea of a patient's eye, and the viewing port may have a wide angle lens, polarizing element or other optical filtering element provided therein.
