Be careful not to use your optical prosthesis? (4,4,3,3)
I believe the answer is:
keep ones eye out
'be careful not' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'your optical prosthesis?' is the wordplay.
I cannot quite see how this works, but
'your' could be 'ones' (I've seen this in another clue) and 'ones' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'to use' is the link.
Can you help me to learn more?
I've seen this clue in the Sydney Morning Herald.
