Picked up in market ten Grolsch glasses (9)
I believe the answer is:
lorgnette
'glasses' is the definition.
(lorgnette is a kind of glasses)
'picked up in market ten grolsch' is the wordplay.
'picked up' says the letters should be written backwards.
'in' indicates the answer is hidden within the clue.
'ettengrol' is hidden within 'market ten grolsch'.
'ettengrol' backwards is 'LORGNETTE'.
(Other definitions for lorgnette that I've seen before include "Pair of glasses with a side handle" , "Handle-mounted glasses" , "Handled glasses" , "Pair of spectacles on ling handle" , "Eyeglasses with a long handle" .)
