What cuts light from space views? Pluto mainly (8)
I believe the answer is:
eyeshade
'what cuts light from space' is the definition.
I can't tell whether this definition defines the answer.
'views? pluto mainly' is the wordplay.
'views?' becomes 'eyes' (I've seen this before).
'pluto' becomes 'hades' (synonyms).
'mainly' means to remove the last letter (virtually or mainly the word, but not all of it).
'hades' with its last letter removed is 'hade'.
'eyes'+'hade'='EYESHADE'
Can you help me to learn more?
(Other definitions for eyeshade that I've seen before include "Visor to protect from strong light" , "screen for lookers in The Sun" , "Protective visor" , "Translucent visor" , "Device to protect sight from strong light" .)
