Answer:
Against the sun I protect your eyes and am often worn on the face of spies
I can be hairy and itchy all over. I hang on a stick. I can be the scariest thing you have ever seen. I stand in the middle of nowhere.
I am your most powerful weapon; I come before your eyes. I help you seek the truth, yet I often give you lies. What am I?
I am whole but incomplete. I have no eyes yet I see. You can see and see right through me. My largest part is one fourth of what I once was.
The faster you run the harder it is to catch me
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
