Name's origin: According to Reed Cundiff, "Climb is named 'Lost Spectacle' since Charles (Bill) Williams lost a lens out of his glasses on the first ascent from the notch around 1956."
Lost Spectacle is a 200 foot pinnacle just to the north of La Luz Trail. A deep narrow notch separates Lost Spectacle from north side of Upper La Cueva Canyon. Mike Hill's guide indicates routes on all sides.
