Laid bare, as Man is blind (5)

I believe the answer is:

swear

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

'is blind' is the definition.
('blind' means 'swear' as in 'effing and blinding')

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for swear that I've seen before include "Assert" , "Vow, attest" , "Asseverate" , "Utter obscenities or take an oath" , "Express annoyance" .)

I've seen this clue in The Times.
