A lens adjusting device (100) includes an optical module (10) and a driver module (20). The driver module includes a seat (22), at least one magnet (24) and at least one winding (26). The optical module is rotatably fixed on the seat. The magnet is fixed on the optical module. The magnet and the winding are positioned at one side of the optical module. A variable current is applied to the winding, and a magnetic field is formed at ends of the winding. The magnetic forces between the magnetic field and the magnet drives the optical module to rotate.
