An eye normally comes in pairs, maybe sometimes a third. They are amazing optical items of the body, none reproductive. Sometimes people say look into my eyes, well, I do not know why they say that you will not see anything. Now if you are on the inside looking out, now that is a different story. You will see so much that some of it you really do not care to see. If you dissect an eye you would find many things, finding a tree, a flower, a person in one probably not. I think the eye like the brain is a very complicated organ, in fact, the whole body structure is complicated.
An eye, look in it and you will not see me, if I look out it I will for sure see you.
