A contact lens cleaning device comprising a ball, a vessel formed with a recessed chamber for housing the lens and the ball, and a vibrator for vibrating the vessel.

After the lens is sandwiched between the bottom concave surface of the chamber, the ball is cleaned when the vessel is vibrated by the vibrator.
