'viewer's complaint' is the definition.
The definition suggests a singular noun which matches the answer.

'local with spotted head' is the wordplay.
'local' becomes 'near'.
'with spotted' becomes 'sighted' (I've seen this before. I am not sure about the 'with' bit.**).
'head' becomes 'ness' (ness is a headland).
'near'+'sighted'+'ness'='NEAR-SIGHTEDNESS'

'causes' is the link.
