What is the function of the developing optical bud?

The developing optical bud, primarily known as the optic vesicle during early eye development, plays a crucial role in forming the eye's structures. It arises from the neural tube and induces the formation of the lens and retina by interacting with surrounding tissues. This process is essential for establishing the visual system, as it initiates the differentiation of cells necessary for light detection and image processing. Ultimately, the optical bud is vital for proper eye development and function.
