Innocent girl rendered unseeing but for that second (7)
I believe the answer is:
ingenue
'innocent girl' is the definition.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ingenue that I've seen before include "she's not spotted" , "Naive young actress" , "Naive young woman" , "Genuine sort of young actress" , "young woman lacking experience" .)
