(under subclass 78.02) Subject matter wherein the composition is used for (1) disinfecting, sterilizing or preserving a contact lens or (2) manufacturing a contact lens using a polymer composition in admixture with a polymer from (1). Such a composition normally would be classified in Class 523, subclass 106, but in most cases, said composition likewise reduces or eliminates eye injury or irritation to the contact lens wearer, or (3) for topically treating the eye of a living animal.
SEE OR SEARCH THIS CLASS, SUBCLASS:
427, in which the ophthalmic drug or ocular device is in a special physical form intended for and adapted to be placed between the surface of the eye and conjunctiva or between the surface of the eye and a lacrimal gland.

8, Bleaching and Dying; Fluid Treatment and Chemical Modifications of Textiles and Fibers,
507, for the process of dyeing a contact lens or product thereof.
351, Optics: Eye Examining, Vision Testing and Correcting, appropriate subclasses for methods of and instruments for fitting contact lenses and structural features and adaptations for contact lenses, such as coloring a portion of the lens to adsorb part of the visible spectrum; 160+, for eye contact lens.
422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing,
1, 43 for generic processes of deodorizing, preserving or sterilizing of contact lenses or compositions thereof.
510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions,
112+, for compositions used for the mere cleaning of contact lenses.
514, Drug, Bio-Affecting and Body Treating Compositions, appropriate subclasses for (1) a contact lens composition which contains a nonbioactive polymer admixed with a medicament or (2) a composition with or without a non-bioactive polymer used to sterilize a contact lens composition to reduce or eliminate any eye injury.
523, Synthetic Resins or Natural Rubbers,
106, for a composition containing an inactive solid synthetic polymer intended for manufacturing contact lenses. This subclass also provides for a contact lens composition containing its own preserving agent when it is clearly specified and restricted for that use. The nominal method of using these compositions for contact with living animal tissue is classified either in this class or in Class 514. See (3) Note in this class (424), subclass 78.02 for more information distinguishing between these two classes.
604, Surgery,
290, for a method of applying a body treating or removing material or subclasses 294+ for a method of application to the eye or eye socket.
