A principal focus or focal point is a special focus: 1  For a lens, or a spherical or parabolic mirror, it is a point onto which collimated light parallel to the axis is focused. Since light can pass through a lens in either direction, a lens has two focal pointsâone on each side.
The center console, because of its location and size, can be considered as the focal point of your carâs interior. After all, this is what your passengers mostly see when they step inside the cabin. And depending on your vehicle make and model, itâs also where some dashboard controls are mounted on.
