Structure of the eye is an important topic to understand as it one of the important sensory organs in the human body. It is mainly responsible for vision, differentiation of colour (the human eye can differentiate approximately 10 – 12 million colours) and maintaining the biological clock of the human body. The human eye can be compared to a camera as both works by gathering, focusing, and transmitting the light through the lens for creating an image of an object.
