They are mounted in twin conical turrets and can move independently of each other, giving the chameleon the ability to see all round itself when seeking prey, and binocular vision in front when it is preparing to strike with its long, sticky tongue.
Scientists at Haifa University, in Israel, tried to find the answer with the help of a computer screen. They do this in two ways. New Caledonian crows—well known for their impressive stick-wielding abilities—show preferences when it comes to holding their tools on the left or the right sides of their beaks, in much the same way that people are left-... While searching for prey, the chameleon uses monocular vision, with each eye functioning independently of the other.
Your brain combines the two to produce a view of the world that appears as though you had a single eye—like the Cyclops from... Finally, under the layer of light-scattering cells is a layer of cells containing granules of a dark pigment called melanin.
All about contact lenses. Native mostly to Madagascar and sub-Saharan Africa, chameleons are some of the most unique-looking animals on earth.
We suggest that in chameleons, eye movements are not simply 'independent,' but are disconjugate during scanning, conjugate during binocular two-eye tracking, and disconjuate but coordinated during monocular one-eyed tracking. A chameleon has a small light-sensitive spot on the top of its head. Well known among nature's best tricksters for their ability to change color to fit their background, chameleons have yet another talent up their lizardly sleeves — eyes that swivel around and appear to be looking in two directions at once.
Their eyes are permanently forward-facing and fixed into their sockets, which is why owls must turn their heads to look around.

The puzzling question was: Called 'voluntary strabismus," this ability enables the chameleon to minimize its body movements to reduce the likelihood of revealing its presence to those it hunts as well as to those that might hunt them. Geckos can see colors around 350 times better than a human, even in dim lighting. Since they also have a more photoreceptor cells than most animals, they have incredible night vision.
That is to say that the creature can move one eye to one direction, and the other eye to a totally different direction at the same time. Male chameleons typically have larger, pointier hoods than females.
George Putic. Much like the chameleon, dragonflies have a 360-degree field of vision, and are adept at avoiding predators. Direct link 264p 4.
That's more common than we realize, they said. So, there you have it!
While the tarsier has the largest eyes relative to its size, the colossal squid has the largest eyes in the animal kingdom. When a chameleon spots its prey with one eye, it swivels both eyes to lock on the target.
