Eyes have sensory elements called "rods" and "cones". The rods are light intensity sensitive. The cones are color sensitive. Predators, especially night stalkers, which are nocturnal, have eyes which are highly sensitive to low light levels. The rods at the receiving end of their eyes are much more sensitive to low light levels, even when the only light available is starlight. This is an evolutionary advantage which allows those predator species to hunt at night in order to catch a meal.
Humans have been daytime hunters, diurnal predators. Our eyesight is more color oriented. As an amateur astronomer, it takes me as much as an hour and a half for my eyes (the rods) to become accustomed to dark skies enough to pick out and appreciate faint light from nebulas and distant galaxies.

∙ 13y agoCats (all of them) have evolved superior night vision and some may have ultra-sensitive hearing, possibly ( look at the antennae of the Serval) ultra-sonic or maybe even sensitive to emf rays (electro-magnetic field).
All animals in my opinion are better than humans because all we do is destroy we at times kill animals for no reason and we wipe out species

∙ 14y agoThe sharpest vision on land would belong to Birds of Prey such as eagles, hawks and buzzards. Such birds possess vision 3-4 times sharper than ours allowing eagles to spot rabbits from several miles away. While hawks and buzzards often scan the earth from a height of 10-15,000 feet looking for tasty rodents to eat! And when they spot one, these birds can dive at over 100mph and, quite incredibly, still keep their target in complete focus.

What advantages does the human eye have over the camera?
Our eyes can see in a wider place or area, while the camera can see only in one position or direction. --- The human eye has an auto-focusing system with a greater range than practically any lens, and a peripheral clarity greater than the average fish-eye lens. The ability to enhance low-light vision through the use of separate black-and-white receptors (cones) gives eyes a low-light night vision, although not on a par with infrared or starlight scopes.
What eyesight is best?
20/20 is the NORMAL vision, not the best. basically a normal person can stand 20 feet from something and see it clearly. so a person who has 20/50 means that they have to stand 20 feet from an object that a normal person (who has 20/20) can see from 50 feet away. if you have 20/200, which is legally blind, you have to stand 20 feet from an object that a normal person can see from 200 feet away...can you fathom that?!?! well it's real. now on the flip side you can be better than 20/20. if i got your eyes checked and the doctor said i had 20/19 vision it would be 1 foot better than 20/20. so basically if you're standing 10 feet from something, i would be able to see the same thing you see from 20 feet away. so theoretically 20/1 would be the best vision possible, but i doubt if that's attainable by a human being. there might be a few animals out there, like the eagle or owl, that have something close to that. cats have good night vision buy i don't think they have good vision as far as distance goes, well not superb like eagles and owls. the best vision possible for a human is 20/10 because of the vision receptors in your iris.it is also the best vision recorded.
What does 20 20 vision mean?

Can grizzly bears see well?

Who has better eyesight a horse or a normal human that is not blind?
Depends on what you mean. Horses can see less detail, but are better at spotting movement. They also have worse depth perception, since their eyes are usually used in a monocular fashion. Conversely, they have a greater range of vision. They have better night-vision than humans, but it takes their eyes longer to adjust.
