Eyes are the organs that allow us to see the world around us. They work like tiny cameras, capturing light and sending images to our brain. Each eye has a lens that focuses light, and the colored part, called the iris, controls how much light enters. Our eyes can detect a wide range of colors and help us notice details, making them essential for everyday activities. In addition to vision, eyes can express emotions. A smile can be seen in the eyes, and they often reveal how we feel, whether happy, sad, or surprised. This ability to communicate through our eyes makes them a vital part of human interaction and connection.
