Vision is the ability to see and interpret the world around us through light. It involves the eyes capturing light rays, which are then converted into electrical signals by the retina. These signals are sent to the brain, where they are processed to create images, allowing us to recognize shapes, colors, and movements. The process of vision begins when light enters the eye through the cornea and passes through the lens, which focuses it onto the retina. The optic nerve then transmits the visual information to the brain, enabling us to perceive our environment and navigate through it effectively.
