Observe using some miniature spectacles (7)
I believe the answer is:
respect
'observe' is the definition.
('respect' can be a synonym of 'observe')
'some miniature spectacles' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'RESPECT' is hidden within 'miniature spectacles'.
'using' is the link.
(Other definitions for respect that I've seen before include "Comply with - deference" , "Show honour to" , "Appreciation" , "Esteem, deference" , "Particular, esteem" .)
