Crossword Genius

Medic examining pupils? (7)

Ross

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" .)

I've seen this clue in The Guardian.
