the camera eye

The "camera eye" is a metaphor describing the human eye's ability to focus light and form detailed images of what we see, similar to a camera lens. It has components like the cornea and lens that direct and focus light onto the retina, which acts like film or a digital sensor. Photoreceptor cells in the retina convert light into electrical signals sent to the brain, creating visual perception. This system allows us to perceive color, depth, and motion, making the eye an extraordinary biological "camera" with sophisticated focus and imaging capabilities.
