Drinks dispenser within vision (5)
I believe the answer is:
optic
'drinks dispenser' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for optic that I've seen before include "What could measure the spirits" , "Visual" , "Spirits dispenser" , "Relating to sight" , "Relating to the eye" .)
