There is quite a bit of fur, skin, muscle, and fat surrounding a bear's skull.

In this photograph of the skull, taken from above, you can see how narrow the brain case is. It lies entirely in back of the eye sockets. It is narrow enough, that viewed from above, you can see it does not extend to the area directly behind each eye socket.
From the front, if the bear is looking directly at you, if you shoot it in the eye, or above or below the eye, you will miss the brain. Notice the bone of the brain case is not especially thick. The bone
