'apparent refinement' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'dried fruit with lenses' is the wordplay.
'dried fruit' becomes 'prunes' (I've seen this in another clue).
'with' becomes 'and'.
'lenses' becomes 'prisms' (I am not sure about this - if you are sure you should believe this answer much more).
'prunes'+'and'+'prisms'='PRUNES AND PRISMS'

'of' is the link.
