Cats have evolved as nocturnal animals, meaning they hunt and otherwise operate during nighttime, while it's dark, and can see many times better than people can in a lot lower light .

Cats cannot see in total darkness, but they can see much better in semidarkness than we, or many other animals, can. This ability is due to the structure of the cat's eye.
. . The clear outer portion that covers the eye is the 'cornea.' This is made up of extremely thin layers of cells arranged in a unique fashion so the cornea is transparent. The cornea allows light to enter unaffected into the eye.

The cat can open his iris (the colored portion of his eye) very wide to let in as much light as possible.

Cats also have a highly developed reflective area in the back of their eyes called the 'tapetum lucidum.' A number of animals, such as deer and raccoons also have this tapetum lucidum. That is what makes their eyes 'glow' at night when our car headlights shine in their faces.

They can see in very low light but not in the full dark. 'Seeing' involves *some* light hitting the eye; the only way to 'see' in absolute darkness like in a deep cave is a kind of sonar like bats use. But their eyes are far more sensitive than ours, they need only a little light to see by and that's how the story came into the world! Besides outside it's rarely if ever *absolutely* dark, not like in caves where there is no light at all.

Cats cannot see in total darkness, but they can see much better in semidarkness than we, or many other animals, can. This ability is due to the structure of the cat's eye. For the size of his head, a cat has extremely large eyes. The eyeball is formed by several layers of tissue. The white part, called the 'sclera,' is made of tough fibrous tissue rich in blood vessels, which transport oxygen and nutrients to the contents of the eye. The clear outer portion that covers the eye is the 'cornea.' This is made up of extremely thin layers of cells arranged in a unique fashion so the cornea is transparent. The cornea allows light to enter unaffected into the eye.

The cat can open his iris (the colored portion of his eye) very wide to let in as much light as possible.

An animal's retina (the back of the eye) is composed of two major types of light-sensitive cells called 'rods' and 'cones.' Rods are responsible for magnifying light impulses. The cat has an increased number of rods. In humans, 4 out of 5 light-sensitive cells in our retinas are rods, in cats, 25 out of 26 cells are rods.

Cats also have a highly developed reflective area in the back of their eyes called the 'tapetum lucidum.' A number of animals, such as deer and raccoons also have this tapetum lucidum. That is what makes their eyes 'glow' at night when our car headlights shine in their faces.

Cats can't see in total darkness, but they can see much better in semidarkness than we, or many other animals, can. Also they use their whiskers to find they way around in total darkness. Like a blind person uses a walking stick.

Yes, in fact they prefer the dark, at least it sure seems like it. Their eyes are made for seeing in the dark. I think in part that is why they like to run around and play when we people have gone to bed for the night.
Take care.

cats can see extremely well in the dark! their eyes are one of the top senses in a cat! (apart from the nose and ears)

Yes they can because I was told by a Vet the harsh light makes seeing harder for cats...
