Student of vision? (5)

Ross

I believe the answer is:

pupil

I'm a little stuck... Click here to teach me more about this clue!

This clue could be a double definition.

'student' is the first definition.
(pupil can mean a student at a school)

'vision?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'of' is the link.

Can you help me to learn more?

(Other definitions for pupil that I've seen before include "One under instruction" , "Scholar" , "One in the eye or in place of learning" , "One being taught" , "bit of a looker" .)

I've seen this clue in The Mirror and The Daily Express.
