The human eye is not suitable for vision in darkness. Most creatures that can see in the dark have special features that help them to do so. Their eyes are usually large, with larger lenses, pupils that can extend to the full size of the eye and equipped with a reflective membrane under the retina that reflect the light that is received by the eye onto the retina to provide a clearer picture. This principle has been used in the making of night vision.devices which use photo detectors or sensors to pick up available light and create pictures that are more vivid.
