Say ‘aye’ too, I agree, seeing this? (3,2,3)

Ross

I believe the answer is:

eye to eye

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

'agree seeing this?' is the definition.
I know nothing about this answer so I can't judge whether this works.

'say aye too i' is the wordplay.
I cannot really understand how this works, but
'i' could be 'eye' (I've seen this in other clues) and 'eye' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for eye to eye that I've seen before include "as one sleuth addresses another" , "a couple of sleuths" , "See this in agreement before charging" , "close up" .)

I've seen this clue in The Guardian.
