![]() ![]() Hydrogen peroxide solutions have a greater ability to fight acanthamoeba keratitis, a rare infection that can cause blindness. This can be beneficial for people who are allergic or sensitive to the preservatives in multipurpose solutions. Hydrogen peroxide solutions do not contain preservatives. Hydrogen peroxide has the ability to penetrate microbial films, which helps create a deeper clean. Significant differences exist between the two. Hydrogen peroxide versus multipurpose solutions īoth hydrogen peroxide and multipurpose solutions remove debris and build-up. After extended use, the platinum coated disk must be replaced. At this point, it is safe to use the contact lenses. After 6-8 hours, the hydrogen peroxide becomes an eye-safe saline solution. This “redox” reaction (reduction and oxidation) produces small bubbles that help to clean the contacts. The contacts are placed into a special container with a platinum-coated disk, which reacts with the hydrogen peroxide. ![]() In order to prevent eye damage, the solution must undergo a chemical reaction before the contacts are placed into the individual's eyes. Burned cells heal very quickly once the natural tear film is restored. While this would not result in permanent damage, it can cause an intense burn that can linger even after an eye rinse. The intention is to prevent the hydrogen peroxide from contact with the eye, which could damage the corneal cells in the epithelium. Hydrogen peroxide is always used alongside a neutralizing product. This enables the solution to break down any proteins that coat the contacts after a long period of use. The majority of hydrogen peroxide solutions are 3% hydrogen peroxide. Hydrogen peroxide contact solutions are storage solutions for contact lenses that rely on hydrogen peroxide to clean the contacts and break up proteins and deposits during the disinfection process. The case is part of a one-step system and includes a catalytic disc to neutralise the peroxide over time. Lenses soaking in a hydrogen peroxide-based solution. ![]()
