Horizontal cells in the eye receive signals from multiple photoreceptors (rods and cones) and enhance contrast, as well as adjust the sensitivity of the photoreceptors to different light levels. They do not transmit signals to the optic nerve or directly form an image, but instead help refine and improve the visual information that is transmitted to other cells in the retina.
