I'm a little stuck... Click here to teach me more about this clue!

'is that illingworth' is the definition.
I know nothing about this answer so I can't judge whether this works.

'with boycott's glasses?' is the wordplay.
'with' means one lot of letters goes inside another.
'boycott' becomes 'ban' (I've seen this in another clue).
'glasses?' becomes 'rays' (I am not sure about this - if you are sure you should believe this answer much more).
'ban' put into 'rays' is 'RAY-BANS'.

Can you help me to learn more?
