Having imperfect vision, the reading's awkward (4-7)
I believe the answer is:
near-sighted
'having imperfect vision' is the definition.
I can't tell whether this definition defines the answer.
'the reading's awkward' is the wordplay.
'awkward' is an anagram indicator.
'the'+'readings'='thereadings'
'thereadings' anagrammed gives 'NEAR-SIGHTED'.
Can you help me to learn more?
(Other definitions for near-sighted that I've seen before include "Myopic" , "Showing lack of vision" .)
