Abstract

A disinfector unit for contact lenses making use of a commercial power source, which can be used corresponding to commercial power source outlets of standards varying with countries and districts, i.e., various types of outlets operable at varying voltages, includes a heater element for receiving a power of varying voltages to heat a contact lens held in a lens case placed in a lens case holder to a predetermined temperature, an electrical controller therefor and a plurality of plugs, each including a case body provided in its one side with a cavity and an electric conductor from which varying types of inserts extend. The plug having the inserts coinciding with an outlet of commercial power used is selected and fitted in the cavity in the case body, and the extending inserts are plugged into the outlet to supply current for predetermined disinfection.
