Most animals see the world around them differently than humans see it – some worse and others far better.
The quality of vision in different members of the animal kingdom varies greatly. Studies have shown that these differences are reflected in the visual field, which is directly related to the way of eating. Animals that are in the food chain as prey have more parted eyes, set higher to the sides, which allows them to see with each eye separately. This allows them to have a much wider field of view compared to their hunters, whose eyes are positioned frontally.
BEE
To make it easier to spot the nectar that hides the flower, nature has given bees the ability to see ultraviolet light (and even more colors of this light). Unlike humans, bees instead have a myriad of small lenses that create “pixels” that allow them to see.
CAT
Cats are nearsighted, which means they can’t see objects that are too far away. I can see shades of blue and green. During the day, their vision is a bit blurred, so they can see up to six times more blurry than humans, while in the dark they can see almost perfectly. Their field of view is slightly wider than that of a human and is 200°.
BIRDS
Birds, in addition to all the colors seen by humans, also see ultraviolet colors, which makes them rare animals that have sharper vision than humans.
BAT
Contrary to popular belief, bats are not really blind. However, in the darkness of the cave, I cannot rely on my own, not very good eyesight. Therefore, in order to detect obstacles in flight, as well as to find the way to the nest and food, bats do not use their eyes, but the so-called echolocation, i.e. broadcast and receive rejected sounds from space .
HORSE
The horse’s eyes are set to the side, so he can see almost 360° around him. Its specific eyeball enlarges all objects, so the horse sees them as much as 50% larger compared to humans. A horse has two blind spots – directly in front of the muzzle and behind the tail, so it is recommended to approach them from the side. In the dark, horses see much better than humans, but they do not see best at dawn and dusk, because then their color perception fades and night vision is not yet activated.
PAS
Dogs can see colors, but in a smaller range than humans (their color scale revolves around cream, white, blue, purple, and gray). Dogs can see a radius of 270 degrees, but the visual acuity of dogs is six times smaller than that of humans.
OKTOPOD
Octopods and squid, unlike humans, do not have a “black spot”. However, they see the world around them blurred and in gray tones, since they cannot distinguish colors.
RIBE
Fish can distinguish colors, and in addition, many of them (e.g., goldfish or piranhas) can see the infrared spectrum, as well as wavelengths of light, which are not visible to the human eye. This allows them to see well in muddy water.
Find answers to the most common questions about laser vision correction, cataracts and lens implantation. Everything you need to know before deciding on a procedure.
No, the procedure is completely painless. It takes only a few minutes, and as early as the next day you can function normally without glasses or lenses.
If you notice that your vision is blurry, colors are fading and you struggle to drive at night, these are clear warning signs. Surgery restores clear vision and once cataracts are diagnosed, it should not be postponed.
The biggest advantage is that you forget about glasses – both for near and far. This means you can read a book, use your phone and drive without additional visual aids.
You absolutely do! Toric lenses are specifically designed to correct astigmatism and provide clear vision.
These are artificial lenses that are placed inside the eye, while your natural lens remains untouched. They are an excellent option for younger people with high diopters who are not candidates for laser vision correction.
