'trouble with viewing' is the definition.
I can't tell whether this defines the answer.

'awful bore spy film' is the wordplay.
'awful' indicates anagramming the letters.
'film' becomes 'pic' (short for picture).
'bore'+'spy'='borespy'
'borespy' with letters rearranged gives 'presbyo'.
'presbyo'+'pic'='PRESBYOPIC'

'having' is the link.
