Doesn’t use Braille music? (5-5)

'doesn't use braille music?' is the definition.
I can't tell whether this defines the answer.

'doesn't use braille' is the wordplay.
I cannot quite see how this works, but
'use braille' could be 'read' (I've seen this in another clue) and 'read' is found within the answer.
The remaining letters 'sights' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
