Golf aim disheartened Clive, thinking seriously about specs (5-3)
I believe the answer is:
pince-nez
'specs' is the definition.
(pince-nez is a kind of specs)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pince-nez that I've seen before include "Glasses that clip onto nose without side-pieces" , "Spectacles clipped to the nose" , "Pair of glasses that clip onto the nose" , "Lenses" , "Clip-on glasses" .)
