Which part of the eye contains rods and cones?

The retina is the key part of the eye that contains rods and cones, which are the photoreceptor cells responsible for converting light into electrical signals that the brain can interpret as visual images. Rods are sensitive to low light levels and are crucial for night vision, while cones are responsible for color vision and function best in bright light.

The retina is located at the back of the eye and plays an essential role in the visual process, as it includes several layers of neurons that help process visual information before it is sent to the brain through the optic nerve. Understanding the function of the retina, including the presence of rods and cones, is fundamental in the study of vision and how sensory systems develop and operate throughout the lifespan.

Other parts of the eye, such as the ciliary body, cornea, and iris, have different functions, primarily related to the structure of the eye, focusing light, and regulating the amount of light entering the eye, but they do not contain the photoreceptors necessary for vision.
