Medic examining pupils? (7)
I believe the answer is:
oculist
'medic' is the definition.
(I know that oculist is a type of medical specialist)
I don't understand the remainder of the clue.
(Other definitions for oculist that I've seen before include "Visionary healer" , "Treater of eyes" , "Person of vision" , "One working with seers" , "Pupils' examiner" .)
