Hamsters cannot see in complete darkness, and their eyesight does not give them an advantage in the dark. Hamsters mainly rely on their sense of smell, hearing, and touch to perceive their surrounding environment. These senses are more acute in the dark and help them move around freely at night. The retinas of hamsters contain a large number of rod cells. These cells can keenly detect changes in the environment in low light conditions, but they can hardly see anything in total darkness or under strong light.
Therefore, hamsters primarily depend on their other senses for orientation and navigation in the dark.
