Cats Have Pupils with Vertical Lines in the Middle

The eyes of the cat turned out to have a variety of uniqueness, here, friends.

Have you ever seen a cat's eye that seems to glow at night when we direct the light into a cat's eye?

It turns out that the cat's eyes actually don't glow when we point the light at their eyes, lo.

In addition to the eyes that look as if they are glowing, there is another uniqueness in the cat's eyes, this is the existence of vertical lines in the pupils of his eyes.

Wow, what is unique about the cat's eyes again? Find out the various uniqueness of the cat's eyes, let's!

Cause Cats' Eyes Look Shining when Exposed to Light

When a cat's eyes are highlighted in a vehicle's headlights at night, for example, their eyes will look as if they are shining and emitting light.

But actually cat's eyes don't shine when exposed to light, friends.

This glowing cat's eye is actually caused by a special and reflective surface or reflecting the light behind the retina of the cat's eye.

This surface that can reflect light is called a tapetum lucidum and has an important function for animals, which is to help them see better in the dark.

Light captured by the eye should be about the part of the photoreceptors that will send information to the brain to convert light into images.

But sometimes the light that is captured by the eye does not hit the photoreceptors, so tapetum lucidum will reflect the light back to be translated into images.

The Color of Light Reflected from Each Animal's Eyes Will Be Different

Besides cats, there are several other animals that can also reflect light through the layer of tapetum lucidum in their eyes. Such as deer, dogs, and other nocturnal animals.

Uniquely, the color of the reflected light will be different in the eyes of every cat, even every animal.

The different colors of light are caused by various factors, including substances present in tapetum lucidum, namely zinc.

In the retina there are also many pigments that will change the color of the light reflected by tapetum lucidum.

The age of a cat can also affect the color of light reflected from a cat's eyes, so cats of the same type may reflect different colors of light, due to different age of the cat.

There are vertical lines in the cat's pupils

Another uniqueness of the cat's eye is the presence of vertical lines in the cat's pupils.

The vertical lines found in these cat pupils apparently affect the ability of the cat's eyes to see and catch light.

With a vertical line on the pupils of a cat's eye, it allows the eye to capture more light than humans, especially when it is dark.

In addition, thin vertical pupils in cats will allow wider muscle movement, allowing more light to enter the eye.

When a lot of light comes in, the cat will squeeze its pupils to become very narrow and in the form of vertical lines.

While in a state of low light, the cat will open its pupils wide to catch more light and can see more clearly.

Can Cats See in Total Darkness?

Cat pupils can actually grow 135 to 300 times compared to humans whose pupils can only enlarge as much as 15 times.

This also helps the cat to catch light in a dark place, so that the cat can see better at night or in low light.

In addition, cats also only need about one-sixth of the amount of light compared to humans.

If a cat can widen its pupils up to 300 times, does this mean it is able to see in a place so dark that there is no light at all at night?

Unfortunately, cat's eyes still need light, even though the amount is very little to be able to see at night, friends.

Cat's Eye Vision Is Broader Than the Human Eye

It turns out that cats can also have vision problems, just like humans, lo.

Cats have nearsighted vision problems, meaning that cats cannot see objects that are far away, and can only see objects that are nearby.

Although cats have this vision problem, but cats have broader vision.

Cats have a vision that reaches up to 200 degrees in width, while a human vision can only reach 180 degrees.

This means, the cat can see objects that are around it more broadly to the side.
