Generally speaking, there are two kinds of cells in the retina of animal eyes that can feel the stimulation of light: one is cone cells, which can feel strong light during the day and distinguish colors; The other is rod-shaped cells, which can feel weak light at night, but can't distinguish colors.

The mouse's eyes have no cone-shaped cells, only rod-shaped cells, so even in the daytime, its vision is very weak. Born with high myopia, he is really color blind. The colorful world is gloomy for mice. This is why rats are not very active during the day, but more active at night.
