nah its not human not by far!! humans have **** eye sight compared to animals.... hmm i think its means over all what aninmal has best sight

Answer 1

It depends on how you define 'best eyesight'.

If you are measuring visual acuity (ability to resolve fine detail), range of colour perception, binocular depth perception, and greatest range of focal depth, then humans definitely do have the best vision of any mammal. Runners up would be some of the other great apes (i.e. chimps), and some of the arboreal frugivorous monkeys.

If you're measuring ability to detect motion, however, then many other mammals are better at detecting contrast changes that indicate something in their perceptive range is in motion. Many herbivores, such as gazelles, deer, and antelope excel at this sort of perception, but their other visual measures are rather poor.

If you're simply measuring range of visual spectrum covered, then I suspect that humans would again be on the top. There are some mammals whose range dips farther into the infrared and ultraviolet than ours does, but none of them can percieve as wide a band of the colour spectrum, from red to violet, that we can.

If you're measuring nocturnal amplification of light to provide the best night vision, then I suspect that the tarsiers would have the best mammalian vision. Their eyeballs are actually larger than their brains, excelling at gathering low light to provide them with enough data to judge distances with binocular vision and find insects in the dark.

But overall, our vision is much better than that of most mammals. Mammals tend to depend more on scent and sound for their sensory cues, rather than on vision. There are many birds that exceed our visual powers, but not mammals.

Answer 2

It certainly wouldn't be humans!

It would depend also on if you mean like the Eagle kind of sight or like seeing in the dark like a wolf, but I don't know the correct answer really for either of these cases.

Then again you might mean the best color vision and that certainly wouldn't be humans either since some animals can see into the ultraviolet range and we can't.

Answer 3

I heard that birds of prey (eagles, hawks, owls, etc.) have excellent eyesight because they can spot a mouse moving around in a field from very high up in the sky.

Answer 4

Interesting that nobody mentioned greyhounds. They can spot a rabbit a mile (literally) away.

Answer 5

If u consider human as an animal....
I think the answer should be human

Answer 6

All primates basically. If you tell perception, then deers, gazelles & all thin ungulates will be on top.

Answer 7

A bigger elephant with out the trunk.
