Examine some plain spectacles (7)

I believe the answer is:

inspect

'examine' is the definition.
(inspecting is a kind of examining)

'some plain spectacles' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'INSPECT' is hidden within 'plain spectacles'.

(Other definitions for inspect that I've seen before include "vet" , "Scrutinize, audit" , "Go over" , "Scan" , "Carefully examine" .)

I've seen this clue in The Times.
