After losing a couple, we became the computer's eyes (6)
I believe the answer is:
webcam
'the computer's eyes' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'after losing a couple we' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
'we' is within the answer.
This explanation may well be incorrect...
'became' is the link.
Can you help me to learn more?
(Other definitions for webcam that I've seen before include "It sends visual images via the Internet" , "Internet-linked camera" , "It records and transmits digital images over the internet" , "eye of surfer" , "Digital camera" .)
