Front component removed from funny eyepiece (6)
I believe the answer is:
ocular
'eyepiece' is the definition.
(I know that eyepiece can be written as ocular)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ocular that I've seen before include "connected with 23 [SIGHT]" , "Relating to eyes or vision" , "Viewer" , "not to be seen - due to this trouble?" , "Connected with the eyes or vision" .)
