It's a genetic adaption to climatic conditions. They have lost the epicanthic fold, which makes their eyes LOOK slanted.
The conditions their ancestors met when first entering that part of the world were:
A lot more wind. A lot more sun glare. And a colder climate which made for a lot more blowing snow grit. All of these resulted over time in those whose folds were minimal living longer (because the blind didn't make it) and passing along this mutation until it became general in the population.
Loss of the epicanthic fold prevents dust and grit from building up around the eye, thus aiding in the prevention of diseases of the eye. The loss also helps the eye to shade out sun glare from the ground.
Hope this helped.

It's called genetics my dear. but if you look at it scientifically, it probably has explanations. Our genes mutated according to the environment, for e.g Western people in cold countries have long sharp narrow nose, cos' the air that passes through that can than be made warmer, as compared to if he had big nostrils, that would send cold air straight to the lungs. How bouut chinese people's small eyes? Could it be due to the fact that they were straining from the sun too much? It' slike, the African americans are black also due to environmental influences, right?
i hope this helped you think about your answer...

Better to see you. How many do you see wearing glasses like the rest of the world.
Other reason why aren't all people red for being in the sun and white when they out in moon light?

everyones eyeball shape is basically the same, its the way it is set in the socket. asians eyes are set further into the socket making them LOOK like they are "shaped different"
Look beyond the physical and see the inner person instead, you will find beauty in every race.
