The 'god eyes' in nature

With the strange observation capabilities that help the eyes of some animals be considered "god eyes". This is an invaluable gift that nature bestows on some species of creatures.

We would be pleased to go to the ophthalmology examination clinics and leave with the results of both eyes being 10/10. However, the human eye has a really limited vision, at least compared to the eyes listed below.

Eyes of the "killer" fly

The eyes of Assasin Fly have a perfect vision.

Above is the image of an "assassin" fly, which is often mistaken for bees, but it is 'far more harmful'. Living in grasslands around the world, the perfect vision allows it to calculate the distance, the speed of objects or prey 'hovering' ahead.

Double eyes with thousands of small 'lenses', give it a superior vision and really work well when hunting smaller insects.

Eagle Eye

An eagle can see a mouse 1.6 km away.

Eagle eyes have the same size and weight as human eyes. But they have a different shape. The back of their eyes is flatter and wider than the back of our eyes, giving it a much larger field of view.

The back of the human eye has a special area in the retina called the visual hole (fovea - where many light-receiving cells are concentrated). The visual hole of the person has about 200,000 cone cells per millimeter, a number so big that you can hardly imagine it, but it has not penetrated the eagle.

Their visual hole has about 1 million cone cells per millimeter . It allowed the eagle to see a mouse 1.6 km away. That is beyond human ability.

Eagle retina is covered with dense cells sensitive to light and called colors are cone more than the retina that enhances the handling of details similar to cameras.

Another small note, the eagles and owls have up to 3 eyelids and the bottom is bigger than above, so we feel they blink up instead of down.

Eye of chameleon

The eyes of the chameleon have an observation of this species up to 360 degrees.

The eye of the chameleon is even stronger than that of the eagle in some 'roughly' in sight.

A unique animal with the upper and lower eyelids sticking together, there is only a small gap to observe. However, with the ability to roll and rotate the eyes independently, the range of this species is up to 360 degrees. The eyes are wonderful.

When focusing the two eyes in the same direction, the gecko's eyesight becomes extremely accurate and has deep awareness, making them able to catch prey with a super speed. The insect a few meters away quickly fell into the range of attack. Chameleon also has the ability to see ultraviolet rays.

Scalloped eyes

Scallop eyes have the ability to produce to replace lost eyes.

The shellfish has many eyes lying along the right and left edges inside the crust. If it accidentally loses a certain eye, it can produce another alternative eye. This is something no other animal can do.

Crocodile eyes

Crocodile eyes have no tears.

" Crocodile Tears" is an image full of judgments in language, because in fact, crocodiles never cry. They do not have a tear gland.

However, the eyes of crocodiles can secrete an oily fluid from the back of the third eyelid or eye membrane, to lubricate or clean the eyes and inhibit the growth of bacteria. The edges of this membrane can be seen at the edge of the eye of the crocodile when it opens. ' Tears' also come from here.

Gecko eyes

The eyes of this small lizard species can be observed very well at night.

The picture above is a picture of a gecko, a small lizard with very big eyes. At night, their pupils are enlarged to receive light, so they observe in the dark better.

However, in the daytime, the pupils only showed a small space. The gecko's eyes are protected by a thin, clean membrane by using their long tongue regularly to lick this membrane.

Snake eyes

Snake eyes do not have moving eyelids.

Unlike other lizard families, snakes do not have moving eyelids , which are responsible for protecting and lubricating the eyes. Therefore, its eyes are always wide open, looking directly at the prey. Therefore, the eyes of the snake are very poor, in return, the olfactory ability ranks first among the animals.

Their pupils are sometimes surrounded by small, colorful circles such as brown, red, yellow or green.

Tarsier monkey eyes

Tarsier's eyes are very large for body size and can be observed very well at night.

This is the smallest type of primate known in the world. The eyes are very large compared to the body size, but it causes less flexibility. However, the neck has the ability to rotate 180 degrees to give it a very good view. The eyes are also really useful when night comes, helping them to hunt very well.

Above are just a few wonderful and strange eyes in nature. It can be said that nature always knows how to make people more humble.
