The photoreceptors, or sensory cells, of the human eye are located in the?

The photoreceptors in the human eye, which include rods and cones, are located in the retina. The retina is a thin layer of tissue that lines the back of the eye and is responsible for converting light that enters the eye into electrical signals. These signals are sent to the brain via the optic nerve, allowing us to perceive 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. This complex process begins when light hits the photoreceptors in the retina, making it essential for sight.

The iris is the colored part of the eye that controls the size of the pupil, but it does not contain photoreceptors. The lens focuses light onto the retina but does not capture visual information. The cornea helps to refract light entering the eye, but like the iris and lens, it does not have the ability to detect light in the way the retina does. Thus, the correct identification of the retina as the location of photoreceptors is fundamental to understanding how we process visual information.
