Dear kid, I doubt that whether you know that parts of our eyes? If you don't know I have to tell you first. Our eyes have the following parts: Cornea, Sclera, Iris, Pupil, The lens, Retina, Blind spot and so on. Do you know what do they do? Cornea is the transparent skin that covers the front of your eye and has no blood vessels. Sclera is the white of our eyes. They are tough skin. Iris controls the amount of light that enters our eyes. Pupil is the hole in the colored iris. It lets light into our eyes. The lens focuses light onto the retina. Retina can show the picture you are seeing. Blind spot is a bit of your retina. If you can't understand this, you can have someone to explain it to you or you can search every part on the internet.
