What is the primary function of the eyes?

The primary function of the eyes is to control vision. The eyes are complex organs that detect light, allowing us to perceive our surroundings through sight. They convert light signals into nerve impulses, which are transmitted to the brain, where they are processed and interpreted as images. This ability to see and interpret visual information is crucial for many aspects of life, from navigation and social interactions to performing tasks and enjoying art.

Other functions, such as circulating blood, controlling digestion, and removing toxins, are performed by different systems in the body, such as the circulatory, digestive, and excretory systems, respectively. These functions are vital for maintaining overall bodily health but are not related to the primary role of the eyes.
