With other cases, a neutralizing tablet must be added. Some storage cases have a neutralizer built-in, making it a simple one-step process. The one-step process neutralizes the hydrogen peroxide solution during the disinfecting stage, while the two-step process neutralizes the solution after the disinfecting stage. One- and Two-Step Processes: How They Work There are two ways to use a hydrogen peroxide solution-a one- or two-step process. The neutralizer turns the peroxide into harmless oxygen and saline, making it safe to put your lenses back into your eyes. Hydrogen peroxide on its own can cause stinging, burning, and corneal damage, so you must follow up the disinfecting process with a neutralizer (the bottle that the hydrogen peroxide comes in has a red tip to remind the patient to not put it directly in the eyes). They are a great alternative for people who are sensitive to the preservatives in multipurpose solutions, and they are highly effective against acanthomoeba, a free-living amoeba that can potentially cause blindness through infection of the cornea.
