Browsing: Eyes

Eyes are complex sensory organs that detect light and convert it into electrical signals, enabling vision—the process by which the brain interprets visual information. Found across a wide range of animal species, eyes vary greatly in structure and function, from the simple light-sensitive spots of some invertebrates to the highly specialized, image-forming eyes of humans and other vertebrates. Human eyes include intricate components like the cornea, lens, retina, and optic nerve, working together to focus and relay visual cues. In science and medicine, the eye serves as both a window into neural processes and a focus of research into aging, disease, and even brain function.
