Abstract
A device for cleaning a contact lens includes a lid, a base portion and a drawer unit detachably coupled to the base portion. The drawer unit includes a container holding a volume of fluid therein. The device also includes a vibration generator for generating an oscillatory motion on the container, where the oscillatory motion induces turbulence in the fluid with sufficient force to dislodge deposits from a lens immersed in the fluid. The device also includes a circuit board secured to the base portion and a light source for generating radiation to disinfect the dislodged deposits in the fluid. A suspension secures the light source to the circuit board and a resonance frequency of the suspension is offset from a frequency of the oscillatory motion.
