It's said I tolerate my contacts, for instance (7)

I believe the answer is:

eyewear

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

'my contacts for instance' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'it's said i tolerate' is the wordplay.
I cannot really see how this works, but
'i' could be 'eye' (I've seen this in other clues) and 'eye' is present in the answer.
'tolerate' could be 'wear' (I've seen this before) and 'wear' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for eyewear that I've seen before include "reading aids" , "glasses" , "viewers' protection" , "Eg, spectacles, contact lenses" .)
