I don't mean to sound patronizing if you already know this, but a lot of people don't.
There is no lens that gives a perspective closest to the human eye. It's not focal length that determines perspective, but rather the distance from the lens to the subject. From whatever distance you are, changing focal length only crops the picture (ie. the angle of view changes). That being said, photographers typically are at certain distances from certain given subjects. The best example is a portrait of someone. The most natural perspective for a head shot from a good working distance is from an 85mm lens to 105mm lens (for a head to a head-and-shoulders shot). For this reason, 85mm has long been called "the lens of natural perspective". If you use a 35mm or even a 50mm lens for the same exact same shot, you will have to be closer to the head, and because you are closer, there will be apparent distortion (because the lens is closer to the nose than it is to the ears, and the closer you get, the more that difference is emphasized by the lens). But if you stay at the same distance, you get exactly the same perspective (the proportions of the head) as with the 85mm lens, except now the head shot becomes a head and torso shot (you have in effect just "cropped" the picture differently).
On the other hand, for many urban or cityscape shots, a 35mm might give the most "natural" perspective. In this case, most of the subject is farther away than someone's head in a portrait would be. Human vision typically has a very wide field of vision (roughly comparable to wider than a 28mm lens even), but, our actual focus is much more limited. Even though we see wide, we concentrate roughly on what an 85mm lens would see - hence, once again, "the lens of natural perspective".
The easiest way to illustrate this concept of distance determining perspective and focal length determining cropping is to use a zoom that goes from wide (28mm) to long. Stand at a given point, focus on medium distant subject, and vary the focal length. You will see that this does not change the perspective at all (the size relationship between objects that are not on the same plane). It only crops the picture more as you go up in focal length. This is because your distance to the subject has not changed.
