human eye
The human eye is a complex organ that allows us to see by detecting light. It has several key parts: the cornea and lens focus light onto the retina, which converts light into electrical signals. These signals travel through the optic nerve to the brain, where they are interpreted as images. The iris controls the amount of light entering the eye by adjusting the size of the pupil. The eye works in coordination with the brain to provide depth perception and color vision, enabling us to navigate and understand our surroundings effectively.
