Is the eye just a hollow ball in your eye socket? Does the eye have tissues like other muscles? How does the eye see? If you get something in your eye, what makes you go blind? What does the thing hit when you go blind? How does natural blindness occur? I am curious about the eye and how it sees.

The eye is a very complex structure. It is not just a hollow ball. The eye has parts that focus light. It has parts that adjust the amount of light that gets into the eye. There is also a nerve layer called the retina that senses the light coming into the eye and relays the picture back to the brain. All of these parts are put together in such a special way as to focus what we see.
Blindness can come from many different causes. Most blindness comes from structural problems inside the eye. If the parts of the eye are diseased or aren't formed correctly, the eye cannot focus and one cannot see. Sometimes blindness comes from problems in the brain. Even if the eyes are normal, these brain problems can cause someone to be blind.
I'm glad to see that you are curious about the eye. The eye is a fascinating organ. You can look at the other areas within the OFCN Eye Clinic to learn more about sight.
