I believe the answer is:
sight
This clue is a double definition.
'see' is the first definition.
(I've seen this before)
'something ugly' is the second definition.

(Other definitions for sight that I've seen before include "something ugly" , "Spectacle; aiming aid" , "The ability to see - spectacle" , "A great many" , "Looking" .)
