Opportunity to use vision? (5)

I believe the answer is:

scope

This clue is a double definition.

'opportunity' is the first definition.
(thesaurus)

'vision?' is the second definition.
(thesaurus)

'to use' acts as a link.

(Other definitions for scope that I've seen before include "Extent; latitude" , "Range; opportunity" , "Extent or reach" , "Range of action" , "Capacity" .)

I've seen this clue in the Evening Standard.
