Eye-protectors (7)
I believe the answer is:
goggles
'eye-protectors' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for goggles that I've seen before include "Tight-fitting spectacles worn for protection" , "Protective wear for eyes" , "Protective spectacles" , "Eye protectors" , "Spectacles worn to protect the eyes" .)
