They're smoked before your very eyes! (10)
I believe the answer is:
sunglasses
'eyes' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sunglasses that I've seen before include "summer wear" , "They relieve effect of glaring" , "These offer a sight more protection" , "viewing aids" , "assumed to protect pupils?" .)
