Hydrogen peroxide is occasionally used as a contact solution. If the hydrogen peroxide comes in contact with your eyes, it is obviously very painful so the hydrogen peroxide is placed in a container with the contacts along with a disk which over 6 hours time neutralizes the solution and it becomes just unpreserved saline solution. Chemically, how does this process work?

H2O2 oxidizes stuff in solution and the oxygen (with a nominal -1 valance) is reduced to a -2 valance in water.

some metals & metal salts (manganese dioxide e.g) cause decomposition of peroxide so maybe the disc contains a small amount of this. It could contain sodium sulphite treated somehow to slowly release.
Hell I don't --- know just guessing!
