Temporarily blind with bright light (6)
I believe the answer is:
dazzle
'temporarily blind with bright light' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for dazzle that I've seen before include "Animal's den" , "Temporarily blind with bright light" , "Overcome with intense light" , "Temporalily blind with intense light" , "glitter" .)
