What might help us see better shows? (10)
I believe the answer is:
spectacles
'shows?' is the definition.
(a spectacle is a show)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spectacles that I've seen before include "See 6" , "Viewing aid" , "(Pair of) glasses" , "shows?" , "Glasses - showy displays" .)
