Abstract: The present invention concerns a process and apparatus for cleaning contact lenses by the association of a thermal treatment with a mechanical vibratory treatment.The thermal treatment is constituted of:a first increase in temperature of the liquid containing the said lenses from the ambient temperature (T1) to a temperature (T2) at which the material adhered to the lenses does not undergo denaturation,a series of stoppages and startings of heating permitting the oscillation in temperature between temperature T2 and another temperature T3 less than T2 and greater than T1,finally a second increase in temperature from T3 to another temperature T4 greater than T2.The vibratory treatment is to be applied in an independent manner with respect to the thermal treatment, either during the entire period between T1 and T2 or during that between T1 and T4.
