It’s a common misconception that ferrets are blind or can only see in the dark. Ferrets have excellent vision and are even able to see in color. However, their eyes are not as well adapted to low light conditions as some other animals. This means that ferrets may have difficulty seeing in the dark or in dimly lit areas.
Ferrets have a tapetum lucidum, which is a reflective layer of tissue behind the retina that helps to amplify light. This makes their eyes shine brightly when exposed to light at night. However, the tapetum lucidum does not work in the same way as human eyes. It reflects light back through the retina a second time, which means that ferrets see a dimmer and less detailed image than we do.
Ferrets also have a narrow field of vision. This means that they can miss things that are happening to the side or behind them. This is why it’s important to always approach a ferret from the front and to make sure that their cage or enclosure has plenty of hiding places.
Despite these minor limitations, ferrets have very good eyesight. They are able to see in color and to distinguish between objects that are close by and those that are far away. Ferrets also have excellent night vision and can often be seen running and playing in the moonlight.
