A method of cleaning and disinfecting contact lenses, including the steps of a) transmitting a ultrasonic energy field toward a pair of contact lenses being suspended in a solution medium in a cleaning cup, causing a cavitation to be produced to remove dirt from the contact lenses; b) keeping the solution medium to be maintained standing still in for about 3-5 minutes for permitting suspended substance to settle to the bottom of the solution medium; c) using heating means to heat the solution medium to about 90° C. for about 15-20 minutes so as to disinfect bacteria and degrade toxic substance carried on the contact lenses; and d) gradually cooling down the temperature of the solution medium to room temperature. The invention relates also to the apparatus for the performance of the method which includes a ultrasonic wave guide and a control circuit board mounted in a housing, a serving container unit mounted in the ultrasonic wave guide to hold a lens holder in NaCl, permitting contact lenses to be cleaned by ultrasonic waves from a ultrasonic speaker and disinfected by heat from a heating rod.
