How Vision Works: Understanding Image Projection on the Retina

The image that your eye sees is projected onto the retina, which is a thin, light-sensitive layer at the back of the eye. The retina is made up of millions of photoreceptor cells called rods and cones, which convert light into electrical signals that are then sent to the brain.

The rods are responsible for vision in low-light conditions, while the cones are responsible for color vision and high-acuity vision in bright light. When light enters the eye, it passes through the cornea and the lens, which focus it onto the retina.

The retina then sends the electrical signals to the brain, which interprets them as images.
