Which Animal Has the Best Eyesight?

AnimalsBiology

Quick Answer

Eagles and other birds of prey have the sharpest vision, with visual acuity roughly 4-8 times better than humans.

The Full Story

Birds of prey, particularly eagles and hawks, have the sharpest vision in the animal kingdom. A wedge-tailed eagle can spot a rabbit from over 3 km away. Their retinas contain about 1 million cones per mm² (compared to about 200,000 in humans), giving them extraordinary resolution. They also have two foveas (focal points) in each eye rather than one, allowing simultaneous detailed vision ahead and to the side. Eagles can see a wider spectrum than humans, including ultraviolet light. Among non-birds, the mantis shrimp has the most complex visual system, with 16 types of photoreceptors (compared to our 3), but this likely aids colour discrimination rather than acuity.

Key Facts

1.An eagle visual acuity is estimated at 20/4 to 20/2, meaning they can see at 20 feet what a human can only see at 4-2 feet.
2.Owls have excellent night vision but relatively poor visual acuity compared to eagles.
3.Chameleons can see nearly 360° and can focus each eye independently on different objects.
