Visual's up to date, putting operator first (7)
I believe the answer is:
optical
'visual's' is the definition.
('optical' can be a synonym of 'visual')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for optical that I've seen before include "connected to light" , "Relating to the eye" , "Relating to vision and light" , "Relating to light/vision" , "To do with sight, perhaps an illusion" .)
