Look at interesting things with Vision C, they say (8)

Ross

I believe the answer is:

sightsee

I'm a little stuck... Click here to teach me more about this clue!

'look at interesting' is the definition.
I can't judge whether this definition defines the answer.

'with vision c they say' is the wordplay.
'with' means one lot of letters go next to another.
'vision' becomes 'sight' (synonyms).
'they say' indicates a 'sounds like' (homophone) clue.
'c' sounds like 'see'.
'sight'+'see' is 'SIGHTSEE'.

'things' acts as a link.

Can you help me to learn more?

(Other definitions for sightsee that I've seen before include "take in views" , "do this in a tourist spot" , "Play the tourist" , "visit the Lions?" , "Visit interesting places" .)
