Surprising sight (3-6)

I believe the answer is:

eye-opener

'surprising sight' is the definition.

This is all the clue.

(Other definitions for eye-opener that I've seen before include "Fact that brings great surprise, dilating optics" , "Startling thing" , "Unexpected revelation" , "A startling enlightenment!" , "Startling revelation" .)

I've seen this clue in the Sydney Morning Herald and The Sun.
