Sort of spectacles not much seen nowadays (5-3)
I believe the answer is:
pince-nez
(Other definitions for pince-nez that I've seen before include "Glasses used to see" , "Glasses fixed to nose" , "Pair of glasses with spring that clips on the nose and no sidepieces" , "Spectacles clipped to the nose" , "Glasses held on by nose clip" .)
