You can get an H202 based solution for cleaning your contact lenses. It comes with a slow release pill that will eventually neutralise the solution so it wont sting your eyes. It turns the solution a slight pink colour so you can tell from looking at them whether they are safe to wear. Dont just use any H202 though, get it from an optician.
Hydrogen peroxide can hurt and harm your eyes and can also cause stinging, burning and cornea (think thats how its spelled) damage.
