I use CS in my wetting drops, in my soaking/disinfecting solution, and wherever 
the lenses are stored. I also add a few drops of peroxide to add oxygen, and 
when I put the drops in my eyes, I slide the lens around a little to put a 
fresh layer of oxygen/CS enhanced water under the lens. It refresehs the eyes, 
adds oxygen, and is a good germ-killer.
