According to Petco, hamsters are nocturnal and can see in the dark. However, hamsters have naturally poor vision and depend on their large, funnel-shaped ears to safely navigate their surroundings. Hamsters are also color-blind.Know More
Hamsters have a limited sense of distance due to their poor vision. In addition to their auditory senses, hamsters use their teeth to determine if certain objects are edible. It is important for hamster owners to take precautions when petting or grooming their hamsters, as it is easy for a hamster to mistake fingers for foods such as carrot sticks. It is also important to keep hamsters protected when they are out of their cages, as their poor vision can lead to accidents.
