Angry viewer has strabismus (5-3)

Ross

I believe the answer is:

cross-eye

'strabismus' is the definition.
(I know that cross-eye is a type of strabismus)

'angry viewer' is the wordplay.
'angry' becomes 'cross' (cross can mean annoyed or angry).
'viewer' becomes 'eye' (organ which sees or views).
'cross'+'eye'='CROSS-EYE'

'has' is the link.
