Eyes

Eyes are organs that detect light. The simplest "eyes", in even unicellular organisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms and may allow the organism to seek out or avoid light. More complex optical systems with resolving power have come in ten fundamentally different "designs", and 96% of animal species possess a complex optical system.

When a person is crying, tears come out of their eyes.

These photos are presented for the purposes of identifying various body parts

-The [[head]] is the body part that contains the brains, the '''[[eyes]]''', [[nose]], [[ears]] and [[mouth]]. The front of the [[head]] (from the forehead to the chin) is called the [[face]]. The head is connected to the [[torso]] via the [[neck]] and the [[spine]].

-The head is the body part in which the human senses of sight, sound, smell and taste are located. It is also important for communication via speech and [[facial expression]]. People reognize other people usually easily by their facial features, which differ among individuals. It is usually also possible to tell the [[gender]] and approximate [[age]] of an unknown person by looking at their face.
+When a person is [[crying]], [[tear]]s come out of their eyes.
-The top of the human head is covered with [[hair]] which, in most people, unlike the hair of other mammals and the unlike the rest of the human body hair, doesn't stop growing at a defined length but has to be regularly cut to the desired length. The top of the head can be clothed with a hat or a cap.
