Survey ship looks defined with this (3-5)

I believe the answer is:

eye-liner

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

'looks defined with this' is the definition.
I know nothing about this answer so I can't judge whether this works.

'survey ship' is the wordplay.
'survey' becomes 'eye' (I've seen this in another clue).
'ship' becomes 'liner' (as in an ocean liner).
'eye'+'liner'='EYE-LINER'

Can you help me to learn more?

I've seen this clue in The Sun.
