Somebody asked me this, when I was in the high school. But do you know purpose of having two eyes? Lets hear your answers.
Too bad you don't have a spare brain, because the one you got is fried boy! You must have got hit will a ball bat when you were young!
So you are saying there were people with one eye, and they got eliminated according to MR Darwin's teory?
Symmetry. Aside from the practical advantages of depth perception, symmetry is seen as the primary factor in determining whether or not a potential mate is attractive. The sexy people got it on and the uglies masterbated in their caves.
We have two eyes because ....... If you thinks you should have only one, you does not need two eyes then you can donate one.
Having two eyes is certainly better than having just one because two eyes provide us with stereo vision and depth perception -- two things that just eye could not give us. With 2 ½ inches separating our two eyes, each eye views an object from a slightly different angle. For instance, if you hold up a flower and look at it with just your right eye, the image is different from the image of when you look at it with just your left eye. The right eye sees more of the right side of the flower while the left eye sees more of the left side of the flower. If you placed the two different images on top of one another, they would not match and our vision would be out of focus. However, our brains sort out these varying visual messages from our two eyes, combines the images, and the recreates one three-dimensional image. This is referred to as binocular vision. Just like your look through two lenses in binoculars, humans view the world through two lenses. The eyes of many other animals are placed differently than ours. Many birds have an eye on each side of their head. Each eye sees a completely separate area stretching out on the left or the right. Viewing the world through two eyes provides us with depth perception. When you look at the flower through just one eye, it looks a lot flatter. Source --
whats even cooler than stereoscopic vision? How about triscopic vision! check out the Mantis Shrimp. It has triscopic vision and a claw that "fires" like a 22 caliber bullet.
I was looking for the keywords stereo vision and depth perception . However, got some interesting answers though.
God created us like that! And if we had only one eye, or three eyes we would find a good explanation for that too.
Two eyes are good. It would be better if one of them was on the front of the head and the other on the back of the head. Parents and dog owners will understand why.
