What are eyes made of?

Question

What is the substance/substances that our human eyes a re made of?

Answer 1

They are all made up of cells but these are cells that are specifically developed to different jobs just like in any other part of your body.  This happens in embryogenesis by stem cells (all with the exact same DNA) migrating to different areas and receiving different hormones depending on where they are.  These hormones act as signals to express certain genes from various chromosomes but not others.  So the same stem cells that give rise to skin or bone give rise to neurons or different parts of the eye.

To see what different parts of the eye are called and what their function is, here are some links.  Generally Wikipedia isn't a good source as it can be altered but as of this moment I can confirm that this page is correct.  Also it's not really a complicated or controversial subject so it's unlikely to be wrong anyway.
