Rod photoreceptors are responsible for vision in low light conditions, such as at night. If someone has poor vision in these conditions, it is likely that their rod photoreceptors are defective. Ganglion cells do not directly detect light and cones are responsible for color vision and high acuity vision in bright light. The cornea is a clear structure at the front of the eye that helps focus incoming light, but it does not contain photoreceptors.
