A varifocal lens device includes a lens unit and a polarization controller. The lens unit has different optical powers for different polarization directions of light. When a light beam is introduced into the varifocal lens device through the polarization controller in a first state, a polarization direction of the light beam is converted by the polarization controller. When the light beam is introduced into the varifocal lens device through the polarization controller in a second state, the polarization direction of the light beam is prevented from being converted by the polarization controller.
