Your eyes are more complex than any camera on the planet!
Cornea: a concave lens on the front of your eye that focuses light Iris: the colored part, a diaphragm that controls how much light comes in (the pupil is the hole the light enters = equivalent to the aperture of a camera) Lens: the "focuser", uses a process called accommodation to focus near to far and make the image as sharp and clear as possible Retina: the sensor, and sends signals to the brain to translate light into an images
Please don't vigorously rub or scratch your eyes, you could hurt them!
