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

'and have repeated vision' is the definition.
I can't judge whether this definition defines the answer.

'notice drink' is the wordplay.
'notice' becomes 'see' (notice can mean to spot or see).
'drink' becomes 'double' (double shot of alcohol).
'see'+'double'='SEE DOUBLE'

Can you help me to learn more?

(Other definitions for see double that I've seen before include "experience an illusion" , "Drunks might well" , "Observe two of everything" .)

I've seen this clue in The Daily Express.
