Most primates have stereoscopic vision but it is especially important to the arboreal ones. Binocular is both eyes being used at the same time and stereoscopic is where depth and distance can be seen. Without it everthing would seem flat and if you were an arboreal primate (predominantely tree based) leaping from branch to branch would be bloody difficult and dangerous. Also most primates rely on their vision rather than smell or touch so this is another reason why binocular, stereoscopic vision is so crutial.
Hope I've helped and it's clear enough.

What are we?
We are humans (Homo sapiens), a member of the taxonomic order primates. In the order primates there are two main sub-orders: strepsirrhini (lemurs, lorises and bush-babies) and haplorhini (tarsiers, monkeys, apes and humans). We are all members of the same order based on certain synapomorphies (i.e., shared, derived traits) that distinguish us from other mammals, which is referred to as the 'primate pattern'. Some of these traits include: forward-facing eyes with stereoscopic vision, grasping hands and feet with opposable halluces and nails instead of claws, larger encephalization than other mammals, a long period of infant dependency and a tendency to give birth to singletons instead of litters, and so forth. As humans, we belonging to the suborder haplorhini. We certainly aren't monkeys as the last poster noted, nor did we 'evolve' from monkeys. Rather, share a last common ancestor with these other priamtes in our distant evolutionary past. The living apes (i.e., Hylobates, Pongo, Gorilla and Pan) shared a LCA with the lineage leading to our own genus at ~ 14, 7, 4 and 2 Mya, respectively.
Is sectoral heterochromia dangerous?
It isn't in most cases. Unless you've acquired the condition due to injury, inflammation, the use of certain eyedrops, or tumors. If you've had it all your life, it shouldn't be a problem. Some people inherit heterochromia. Read more: http://en.wikipedia.org/wiki/Heterochromia
What does it mean if you are left handed and left eye dominant?
You are fortunate to be left handed. Do you have a ridge at the back of your skull? You may be descended from Neanderthals whose brain was 20% bigger than Homo sapiens. You are probably musical but can't read music ,good at art and see the world a bit differently to the herd. Left eye dominance means that although you see the world in stereoscopic vision your left eye is the brain's reference signal that prevents blurring of images. Experiment Look at your index finger at arms length, close left eye first , then open and close right eye. Repeat this test and check what eye causes your finger to move. The eye that keeps it in the same place is the dominant eye.
Why do human beings have two eyes?
we have two eyes becsuse imagine if we just had one - its extremely difficult to see things around you with two eyes, you can see things in front of you and all around you with one eye, we would have to keep turning our heads to see things around us.
Are people blind before age three - since most people can't remember being born?
Babies develop excellent vision by about one month old. In the first few years of life, the brain lacks the ability to form long-term memories. This may account for the fact that people cannot remember their own birth.
What are animals with opposable thumbs and binocular vision called?
Animals with opposable thumbs and binocular vision are called primates. This group includes humans, apes, and monkeys. Their opposable thumbs and binocular vision are important adaptations for grasping and manipulating objects in their environment.
What animals have opposable thumbs and binocular vision?
all primates
Is binocular vision a characteristic of all primates?
Yes, binocular vision is a characteristic of all primates. It helps in depth perception and enables them to accurately judge distances. This trait is particularly advantageous for primates living in complex environments such as forests.
What animal groups have have opposable thumbs and binocular vision?
all primates
What are two distinctive features of all primates?
Two of the distinct features of all primates were grasping fingers and toes with nails. Another is forward facing eyes for binocular vision.
Do lemurs have binocular vision?
Yes, lemurs do have binocular vision. This means that their eyes are positioned close together on the front of their face, allowing them to see depth and judge distance accurately. Binocular vision is common in many primates, including lemurs.
What group of mammals with binocular vision?
Primates are a group of mammals known for having binocular vision, which allows them to perceive depth and distance more accurately. This adaptation is particularly beneficial for navigating complex environments, such as forests, where depth perception is crucial for climbing and foraging. Binocular vision is also a characteristic feature of other mammals, such as some carnivores, but it is most pronounced in primates.
Is eagle has stereoscopic or monocular vision?
Stereoscopic vision
Do monkeys have binocular vision?
yes all primates have binocular vision which allows them to have better depth perception
Do rats have monocular or stereoscopic vision?
stereoscopic
What is the most ancient distinctly primate behavior a monogamy b violence c social grooming d nursing the offspring e binocular stereoscopic vision?
D. Nursing the offspring. This is a general mammal trait, much older than actual primates. Then comes either violence or social grooming, though neither occurs in all primates. Then binocular vision (general primate trait associated with living in trees) and then monogamy, potentially, though that occurs only in a very few species and then not even in the entire species (an example being humans ;)).
Why do lemurs have binocular vision?
Lemurs have binocular vision because they are raccoon monkeys
