For seeing sights? (10)
I believe the answer is:
spectacles
This clue could be a double definition.
'for' is the first definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'sights?' is the second definition.
(I know this)
'seeing' is the link.
Can you help me to learn more?
(Other definitions for spectacles that I've seen before include "shows?" , "See 6" , "What would make some people see better" , "(Pair of) glasses" , "Aid to vision" .)
