The light rays the wave of the lights hits through the cornea the clear front “WINDOW” of the eye. The cornea bends the light rays in such way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The iris works like a shutter of a camera. The retina gets the light ray and gives it to the optice nerve which will send you signals to the brain.

    I really love how you went a extra step and took pictures of the iris and the retina. I can see the picture very clear and you clearly state where all the parts of the eye. I think that your description of the eye was very good too because of how you described the eye as a camera.

    Hana, your pictures are really clearly labeled. Remember to include the lens, and its important job of focusing and flipping light waves.
