Use this current topic, vision, and explain it. In addition describe what learning techniques you used to master the material.
Vision or sight is the perception of objects located in the environment based on the light that they emit or reflect. Light is visible electromagnetic radiation. Human vision is adapted to take advantage of the most available source of electromagnetic radiation: solar radiation. UV and infrared are both outside the light range perceived by the human eye. Images are formed by refraction or the bending of light rays.
The eyeball sits in the orbit or eye socket. It is controlled by a number of different muscles, and cushioned by orbital fat. Eyelids and eyelashes help to protect the eye. In order to understand the sense of vision, you do need to understand the anatomy of the eye.
