A piezoelectrically driven optical lens includes a lens body and a piezoelectric element for generating a rotating force. The lens body includes a hollow base; a lens barrel rotatably positioned in the hollow base; and a lens system disposed in the lens barrel, axially movable by rotation of the lens barrel and configured for zooming or focusing. The piezoelectric element is secured in position in the hollow base and in contact with the outside of the lens barrel to generate a rotating force for rotating the lens barrel. Accordingly, with this simple structure of the piezoelectrically driven optical lens, a drawback of the prior art, that is, structural complexity, can be overcome.
