The light rays from an object pass through the lens of the camera and get recorded on a film or a computer chip. Do you notice something about this drawing? Yes, the picture that is recorded by the camera is upside down (of course, when you look at the picture as a printed photo or on a computer screen, it is not upside down.) How your eyes work Your eye works in a similar way to a camera - light passes through the lens of your eye and is 'recorded' on the back of your eye (the retina). Iris (eye-ris) The iris controls the amount of light that enters the eye. The iris is the coloured part of your eye.

Cornea (Cor-nee-a) This is the see-through skin that covers the front of your eye. It is clear like glass and it has no blood vessels in it. Pupil (pew-pil) This is the hole in the coloured iris. It lets light into your eye. It gets very small in bright light, and bigger in dull light. Optic nerve (op-tic) The electrical messages from the retina travel along the optic nerve to your brain. It's a bit like the cable that carries all the TV pictures

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
