The 3-D vibration technology is a patented technology used in the VueSonic automatic lens cleaner for better cleaning. The 3D multi-frequency modulated stereo power source and corresponding intelligent control circuit use digital and analog control program to enable uniform and stable three-dimensional force distribution in the silicone cushion and damping heads” (3D = rotation force, left and right force, up and down force), can rub and clean the lens 360 degrees without any missed angle.
