Egg is the answer
I am near, I am far I am big, I am small I can't see nor can I talk. In your eyes I reside and affect your feeble mind. Watch closely and then step back, did you miss me? I'm not behind your back,
What am I?
I am used for light yet I am solid. Without me you would feel enclosed. I hate being touched, especially with a lot of force. I like to be in buildings. What am I ??
