What may improve view of people like Deighton? (4)
I believe the answer is:
lens
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for lens that I've seen before include "Bender of beams" , "One focusing light" , "Piece of glass in optical instrument" , "Light-gathering device of a camera" , "City of northern France: periscope part" .)
