Compositions, and methods useful for making such compositions and for using such compositions, which are useful to de- stroy hydrogen peroxide in a liquid aqueous medium, such as that used to disinfect contact lenses, are disclosed. The composition comprises at least one item containing a hydrogen peroxide destroying component, e:g., catalase, effective when released in a li- quid aqueous medium to destroy or cause the destruction of hydrogen peroxide present in liquid aqueous medium, and a barrier costing located on at least one item and acting to substantially prevent the release of the hydrogen peroxide destroying compo- nent for a period of time after the composition is initially contacted with a hydrogen peroxide-containing liquid aqueous medium. The barrier coating comprises a water soluble coating component, e.g., hydroxypropylmethyl cellulose, and is formed by a meth- od which comprises applying a mixture comprising water, a ketone and the water soluble coating component to produce at least one precoated item; and removing water and ketone from the precoated item or items. In a preferred embodiment, the composi- tion includes a cleaning enzyme to remove debris from the contact lens, in particular at the same time the lens is being disinfect- ed.
