What is the part of the eye responsible for transmitting images to the brain?

The retina is a crucial part of the eye that plays a key role in vision by transmitting images to the brain. It is located at the back of the eye and contains photoreceptor cells known as rods and cones. These cells are responsible for converting light that enters the eye into electrical signals. Once the light is transformed into these signals, the retina sends the information through the optic nerve to the brain, where it is interpreted as visual images.

The cornea, while important for focusing light entering the eye, does not transmit images; instead, it primarily assists in bending and directing light toward the retina. The iris, which is the colored part of the eye, functions to regulate the amount of light entering the eye by adjusting the size of the pupil. The choroid is a layer of blood vessels and connective tissue between the retina and the sclera that provides nutrients and oxygen to the retina but does not directly contribute to the process of transmitting images. Thus, the retina is distinct in its function as the actual site for image processing and transmission to the brain.
