The lens in the human eye plays a crucial role in the process of vision. It helps focus light onto the retina, located at the back of the eye. By changing shape through a process called accommodation, the lens adjusts its curvature to control the focal length, allowing the eye to focus on objects at varying distances. This ability to refract and focus light ensures that a clear and sharp image is formed on the retina, facilitating the conversion of light signals into neural impulses. The lens, along with other components of the eye, contributes to the formation of a visual perception.
