Hello Dear.

Line Joining the Center of Curvature is the Principle axis of the lens and it is always Straight.The Principle axis also passes through the Optical center of the Lens. It can extend on either side of the Lens.

The straight line of the Principle axis never changes whether the medium on either side of the lens changes, or the Focal Length of the Lens changes.
