Human Vision

Human vision is the process by which our eyes and brain work together to interpret light reflected from objects. Light enters the eye through the cornea and lens, which focus it onto the retina at the back of the eye. The retina contains specialized cells called photoreceptors (rods and cones) that convert light into electrical signals. These signals travel via the optic nerve to the brain's visual cortex, where they are processed into images. This system allows us to perceive color, shape, depth, and movement, enabling us to understand and navigate our environment effectively.
