Cats don't need lights in the dark
Does your cat need electricity when you go out or leave it at home? Cats seem to have special kind of eyes that allows them to see in the dark. Why can cats see in the dark? How do you see in the dark Here are some reasons why a cat's eyes glow.
Cats are okay in the dark
No electricity is required
When you leave your cat at home, you don't
have to turn on the light and go out saying, "I'm sorry if it's pitch
dark." Cat eyes are said to be nocturnal, and they are more active in
dim light than in bright light.
Cats may become stiff and unable to move due
to the stimulation of strong light. Cats don't have to worry about not
being able to see the toilet or food even when the lights are turned off in the
house.
Cat eye size
Cats can see in the dark because of the size
of their eyes. A cat's eyes are characterized by its large
eyes. Cats have wider pupils than humans, which allows more light to
enter. Therefore, the cat's field of vision allows it to use light
effectively even in the dark.
Can’t see in the dark
Cats are said to be able to see in the dark, but they cannot see in the dark. You will be able to see in the dark by efficiently capturing the faint light coming through the window and the slightest light such as moonlight. Cats are fine in the dark as long as there is a little light source.
Twice as much use of the retina
The fact that cats can see in the dark seems
to be related to the amount of light hitting their retinas. Cats have
reflectors in their eyes called the tapetum. Because the tapetum is
excellent, the light that passes through the retina is reflected by the tapetum,
and the light is taken into the retina, increasing the amount of light.
The cat's eyes are able to see even in the
dark because the tapetum makes efficient use of light. Also, cats cannot
distinguish between colors, but they cope with darkness by distinguishing black
and white from their retinas.
What do cats look like in the dark?
Cat eyes are nearsighted
Cat’s eyes are said to be nearsighted. Cat’s
eyes see things up close. A cat's visual acuity is said to be about 0.1 to
0.2, and it seems that it can see clearly only up to 10 meters away.
Cats have poor eyesight, but their ability to
catch prey in the dark is due to their good dynamic vision. Cat’s eyes are
vague and blurry, but they have the ability to respond to rapid changes in
light and shadow.
Cats are said to be able to hunt even in the
dark due to their excellent dynamic vision and instantaneous power.
Cat's eyes grow in the dark
If you look at a cat in the dark, you can see
its large, round eyes. A cat's eyes take in light from the black
eye. So, in places with a lot of light, the eyes are narrow, and in places
with little light, the eyes change greatly.
Howling cat
If the room is darkened, cats may meow, get
scared, or act violently. Kittens often cry at night, turning off the
lights and getting lonely and crying when it gets dark. It is said that a
cat that is not accustomed to one person may become scared and hide in the dark.
Cats that don't play enough will turn off the
lights at bedtime and when it's dark, the sports day may start. Basic cats
are fine even in the dark. Even cats that are not used to the dark can get
used to their owner's lifestyle and the dark space.
Until the cat gets used to it, it is safe to
keep the owner visible and watch over the cat until it falls asleep.
Why Cats Eyes Glow in the Dark
Glowing eyes are due to tapetum
As explained above, the tapetum reflector is
the reason why the cat's eyes shine. The reason why the eyes glow in the
dark is that the retina reflects the light that enters the retina, causing the
eyes to glow.
Even weak light bounces off, so the eyes glow
even in dark or bright places. In other words, if a cat is in the dark and
you gently open the door, the cat's eyes will appear to glow.
Cat's eyes glow with flash
The phenomenon that the eyes glow when you
shine a light on a cat in the dark is also a flash when taking
pictures. Cats are dark and their pupils are always dilated. A sudden
strong light (flash) enters the eye, resulting in a photo of the cat's eyes
glowing.
The pupil adjusts the light
A cat's eyes glow in the dark because its
pupils regulate the amount of light. In bright light, the pupil narrows to
prevent excess light from entering. On the other hand, in darkness, the
light becomes weaker, so the pupil widens to collect more light.
That's why a cat's eyes glow in the dark.
Summary of cats and darkness
Cats can be said to be fine in the dark
without lights. Cat’s eyes are not just big; they also have the ability to
cope with darkness. Cats adjust the light by dilating and narrowing their
pupils.
The cat's tapetum makes effective use of
light. The tapetum allows the reflector to reflect light and make the eye
shine. A cat's vision is characterized by blurring when looking at close
objects.
Cat’s eyes can only distinguish between black
and white, even in the dark, so there is no need to distinguish between colors.
The cat's dynamic vision and hearing allow
it to react to quick movements, so it can hunt even in the dark. I think
the cat's eyes have a special ability to cope with darkness even if their
eyesight isn't very good.
