Range or field of vision (4)
I believe the answer is:
view
This clue is a double definition.
'range' is the first definition.
(I know that view is a type of range)
'field of vision' is the second definition.
(thesaurus)
(Other definitions for view that I've seen before include "Aspect - prospect" , "extent of visibility" , "Sight - opinion" , "general survey" , "Opinion - vista" .)
