Eccles taps out things you need to see (10)
I believe the answer is:
spectacles
'you need to see' is the definition.
I can't tell whether this defines the answer.
'eccles taps out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'eccles'+'taps'='ecclestaps'
'ecclestaps' is an anagram of 'SPECTACLES'.
'things' is the link.
Can you help me to learn more?
(Other definitions for spectacles that I've seen before include "they make things easier to read" , "(Pair of) glasses" , "With which to view" , "Aid to vision" , "splendid entertainments?" .)
