Answer:
I do not have eyes but I once could see. I used to have thoughts but now Iβm empty.
I am a word. I become longer when the third letter is removed.
I am the only word that looks the same when spelled upside down.
I wonβt break if you throw me off from the highest building but I will break if you place me in the ocean.
I am slim and tall many find me desirable and appealing they touch me and I give a false good feeling once I shine in splendor but only once and then no more for many I am to die for.
No matter how little or how much you use me, you change me every month.
