The eye relies on the retina to function

To human eyes, the world at night is a formless canvas of grey.Many nocturnal animals, on the other hand,experience a rich and varied world
bursting with details, shapes, and colors.What is it, then, that separates moths from men?Moths and many other nocturnal animals
see at night because their eyes are adapted to compensate for the lack of light.All eyes, whether nocturnal or not,depend on photoreceptors in the retina to detect light particles, known as photons.
