There are two main types of contact lens cleaning solutions: hydrogen peroxide-based solution and multipurpose solution. Both cleaning solutions aim to remove debris and build-up. However they work in different ways.
Hydrogen peroxide-based solution is used for disinfecting, cleaning and rinsing the contact lenses. It should be effective against COVID-19 viruses. However, special care is needed while using this solution since hydrogen peroxide can cause severe irritation and eye damages. To use it safely, the lenses must be placed in the provided case filled with solution to clean and disinfect the lenses. After the disinfection and neutralizing step is completed, which normally takes an hour, the lenses can be removed from the case. Rinsing the lenses with hydrogen peroxide solution and applying them directly to the eyes without completing the entire disinfecting and neutralizing step must be avoided and all given instructions must be strictly followed.
Multipurpose solution is used for daily cleaning, rinsing, disinfecting and storing the lenses. All purposes are obtained from the same solution. Since direct contact to this solution does not cause eye irritation, thus no special care is needed. However, in multipurpose solution and ultrasonic cleaners, there is currently inadequate scientific evidence to determine efficacy against the virus.
