If your eyes do make contact with hydrogen peroxide, make sure to immediately flush it out with sterile saline. Since the neutralizing disk loses its effectiveness over time, it is critical to regularly replace it. This chemical reaction produces bubbles inside the case as it undergoes the transformative process over a period of several hours. Included with every solution bottle is an upright contact lens case containing a platinum-coated disk that chemically reacts with hydrogen peroxide to decompose it into a safe, non-irritating, sterile saline solution.
Since hydrogen peroxide is a chemical that causes stinging and burning when it touches the eye, after the contacts have been disinfected the solution must be neutralized to be healthy for your eyes. Moreover, hydrogen peroxide is more effective at battling acanthamoeba keratitis (an eye infection that may lead to blindness) than all other types of contact lens solutions. This solution thoroughly breaks up the proteins and removes deposits on the lenses during the disinfection process, which can be beneficial for people who tend to accumulate large amounts of build-up on their lenses. Hydrogen peroxide solutions, such as Clear Care® by Alcon or Refine One Step™ by CooperVision, contain no preservatives or allergens. Their convenience and low cost make them a popular choice. Multipurpose solutions are straightforward and easy to use only one solution is needed to rinse, clean, disinfect and store your contacts (as seen in the image). As an added benefit, hydrogen peroxide does not contain preservatives - which can be particularly beneficial for those with allergies or eye sensitivities. While both remove debris and build-up, and disinfect lenses, only hydrogen peroxide is capable of penetrating the microbial biofilms for a deeper clean.
There exist 2 different types of solution for contact lenses: Multipurpose and Hydrogen Peroxide-based. Once you and your doctor have decided on the type of contact lenses you'll need, it's time to choose the most suitable contact lens solution for your eyes and contacts.
