No organic optical sensory organ functions without some light. But, cats have some built-in mechanisms that help them see much better in less light than humans can. Here is a quick, easy read about cat vision.

Cats have an elliptical pupil which opens and closes much faster than round types and allows for a much larger pupil size. This allows more light to enter the eye. Cats also have a mirror like membrane on the back of their eyes called a Tapetum. It reflects the light passing through
the rods... back through the rods a second time, this time in the opposite direction.
The result is a double exposure of the light, which permit cats to see well in near darkness.
Although a cat cannot see in total darkness, a partly cloudy night sky with some stars will provide enough light for cats to hunt and see movement, even in the cover of most brush. At nigh, a cat relies on it's extremely sensitive hearing and directional ear movement to locate the general position of prey, then targets and captures the prey using it's keen eyesight.
The yellowish glow you see when you shine a light into cat eyes at night,
is really your light reflecting off the Tapetum membrane.

Cats , and big cats such as the tiger etc, has excellent night vision, as they predominantly hunt during the night hours. Check out the eyes of a cat in the night time, see how the pupils become larger.

Define dark. Total darkness? Then no. They are able to see better with less light though.

they can't see if the dark is total, they need a source of light to see, even a very small one.
If you got a digital alarm clock which provide some light, it's enough for your cat to see, even if for you it's total darkness.

cats are nocturnal animals they see better in the dark than they do in the light. it allows them to become great predator hunters.
