The human eye is an amazing organ of the body. Complex and sophisticated. This essential organ regulates our sense of sight and helps us interpret the shapes, colors and dimensions of objects by processing the light. Understanding the anatomy, structure and optics of the eye makes us appreciate the importance of our eyes.
