10 interesting facts about lion eyes

Lioness eyes focus, looking up

If there’s one animal that truly captures the essence of Africa, it is the lion. Lions are one of Africa’s most iconic animals. Admired throughout history, these large cats serve as a symbol of bravery and strength.

Lions have powerful bodies. They are the second largest cat species, after tigers.

In addition to their large size and sheer strength, the lion population is also renowned for its impressive eyesight. This is an advantage for their predominantly nocturnal hunting.

There are several reasons for the lion’s excellent vision. Below are ten interesting facts about lion eyes – one of their greatest hunting tools.

Lion Eyes Close Up: 10 Roarsome Facts

Much like crocodile eyes, a lion’s eyes serve as an exceptional piece of equipment.

A lion’s eyes help them hunt, especially at night.

Let’s take a deeper look into the eye of the lion.

1. Inside a lion’s eyes

Lions have significantly more rod cells than cone cells in the retina of their eyes, especially when compared to humans. Lions have around 25 rods to each cone, while humans have about 4 rods to each cone.

The rods aid the reflection of more light into the eye, while cones are for color vision. This is what contributes most to the lion’s impressive nocturnal vision. These large cats can see 6 to 8 times better than humans in low light conditions.

Regarding cones, there are three types – namely blue, yellow, and red. Lions, like all cats, only possess the cones for short waved light (blue), and medium waved light (yellow). They cannot distinguish red colors.

2. Lions’ eyes shine

If you’ve gone game viewing at night, you may have noticed some glowing eyes looking back at you.

Lions, like most nocturnal animals, have something inside their eye known as tapetum lucidum. This is a reflective layer of cells behind the retina which acts as a mirror.

The rod and cone cells absorb light entering the eye. The tapetum lucidum reflects the light which passes through the retina and photoreceptor cells.

This gives the lion’s brain two chances to absorb the light waves and refine the image. This significantly improves the animal’s night vision.

3. Outside a lion’s eye

The outside characteristics of a lion’s face play a significant role in its incredible night vision.

The white stripe under its eyes helps reflect faint light into the eyes, making it easier to see under low light conditions.

It also helps in mottled lighting, common in dense, bushy areas.

This unique feature is a good indication that lions are nocturnal.

If you look at a cheetah, you will notice they have black tear-like markings. This reduces glare, which is ideal as these quick, spotted cats tend to hunt during daylight.

4. Lions have a second eyelid

Lions have a second eyelid known as a nictitating membrane. This serves as an extra layer of protection for the cornea.

It also moistens the eye while maintaining vision.

The nictitating membrane acts as a windshield wiper, removing dust and anything else blown into the lion’s eye.

5. Lions have round pupils

Most felines have vertical slits instead of round pupils. This is to maximize the capacity of recognizing the depth of a field.

Smaller cats need to crouch to get close to their prey before pouncing. Vertical slits are important as they help these cats measure shorter distances precisely.

Larger felines, like lions and tigers, have round pupils.

As they have longer legs, their eyes are at a greater distance above the ground. They are also a lot more powerful and can jump much further.

Lions do not need to get too close to their prey before pouncing and do not require a vertical pupil.

The round pupils possessed by larger felines are also known to allow more light to filter into the eye, giving them better night vision.

6. What color are lions’ eyes?

Lions’ eye colors are typically brown or amber. Even white lions, whose fur lacks the typical lion’s pigment, have a pale amber eye color (NB: some white lions have blue eyes).

As previously discussed, the anatomical structure of a lion’s eye is responsible for the eye shine we often see when game viewing at night.

The typical color of this eye shine is a red or gold hue. This can vary depending on the angle at which one views the lion.

7. Baby lion eyes

Baby lions, referred to as “cubs,” are born blind. They do not begin to open their eyes for the first 3 to 4 days after being born. Even after opening their eyes, they cannot see very well and need extra care from their mums.

Their eyes start out blue-grey and begin turning brown or amber around the 2- to 3-month mark.

8. Lion eyes and hunting

Given their impressive night vision capabilities, lions generally hunt at night. By using their vision, lions hone in on their target, coordinating their attack based on where they see their prey moving.

In a hunt and evasion scenario, sight is the most crucial factor. Lions’ prey also possess strong senses such as sight and smell, which helps them escape.

Dodging obstacles and handbrake-turning past members of a lion pride makes certain prey tougher to catch.

The key to a lion’s hunting success lies in having the conditions skewed in their favor. This is most commonly at night, long after the sun has set, and when everything has become completely dark.

Lions also hunt well during storms as the noise and wind make it harder for their prey to hear or see them.

9. The full moon can hinder a lion’s vision

As examined earlier, the darker it is, the better it is for lions. A full moon makes it easier for prey to detect and escape predators.

During a full moon, lions will often put off hunting while the moon is at its peak. They will much rather wait until the moon begins to dip over the horizon or until clouds have covered it.

10. Lion eyes positioning

Unlike much of their prey, lions have binocular vision. This suggests that their eyes point forward, allowing them to judge depth more effectively. While this is a great advantage, their eyes cannot move from side to side very quickly.

Lions have to move their entire heads from side to side to see in different directions. On the other hand, their prey has eyes on the sides of their head.

This provides their prey with a wider range of vision. It also hinders their ability to resolve single objects after dark.

For this reason, when night starts closing in, these animals move out into open clearings for increased visibility and room to move if need be.

More Incredible Lion Facts

In addition to their unique eyes, lions have many other characteristics and traits that are sure to impress you.

Below are a few mind-blowing facts about one of Africa’s largest cats.

Lions can get their water from plants

Lions are highly adaptable and can survive in very dry areas. In places like the Kalahari desert, they get most of their water from their prey and plants such as the tsamma melon.

Lions are big eaters

These large felines can consume up to 40 kg of meat in one meal, which is generally a quarter of their body weight.

To assist them in scraping flesh off the bones of their prey, they have tongues with sharp, pointed rasps, papillae.

Here is more information on what lions eat.

Lions roar together

Unlike other cat species, lions roar together, often to mark their territory.

A calling typically goes on for about 40 seconds.

The entire pride joins in, including the younger cubs with their tiny mews.

Lions are quick and powerful

These large cats can run short distances at 80 km/h and leap as far as 11 meters.

This, coupled with their impressive vision, makes them one of the top predators of Africa.

Lions love sleep

Lions enjoy lazing around. These big cats spend 16 – 20 hours sleeping each day. They have few sweat glands and conserve their energy during the day.

They are much more active at night when it’s cooler. This is also when they hunt.

What Are Your Thoughts on the Lion Eye?

Lion eyes are an incredible tool and are largely why lions have a relatively good hunting success rate. In sheer darkness, where most of us would find ourselves lost without being able to see a thing, lions move with ease.

While their eyes are highly functional, they are also beautiful with their brown-amber color.

For your next game ride, consider heading out after sunset. It is then when these large cats are most active.

It is also when you will notice their shining eyes.

Just hope that they aren’t angry lion eyes.

    This is very important topic because there was few things which i did not know how eyes works in the dark and it is excellent.

    1. Let us not provoke the beast wirhin man to go game hunting for these amazing Afican animals.
      Omit lions, tigers, zebras, giraffes elephants & especially any species threatened with extinction from any gaming expedition.
      These creatures are vital and homesake to the land.
      Humans must respect life, not hunt it.
      Please augment your informative post with this update.
      Go on safari to see with our eyes, (capturing only photographs & memories) the stealth endurance & power of African animals, then leave it all, as it was: intact.
      Enjoy =’s Not destroy .
      Co~existing with nature is mans’ life lesson. 🙂
      Thank you for your spirit of discovery & knowledge.
      Remember, Eyes have a soul residing behind those pupils..

      1. The Wilder Beast

        Thanks for your sentiment. However, the biggest threat to all of those creatures is the loss of their habitat. Furthermore, they pose a very real danger to humans who live nearby.
        The balance we should be searching is that one that makes them and their land economically viable so that people who do protect them can make a profit off them. It this means taking thousands of dollars off some idiot who wants to shoot one, so be it.
        And, finally, lions, elelphants, rhinos are African animals. I strongly believe it should be up to Africans to decide what to do with this resource. No one would ever suggest reintroducing wolves, lynx or bears into London.
        There is no simple answer to protecting these majestic creatures, but we have to put more pragmatic thought into how that can be done.
