Use a one-step peroxide-based cleaning regimen such as Clear Care. Do NOT use any of the multi-purpose products that are available on the market as these have been formulated essentially for use with disposable lenses, not lenses that you want to nurture for up to a year. Such products are quite aggressive and will therefore quite possibly cause damage to any lens that has been tinted, printed, painted or treated in any way.
Additionally do not clean of our contact lenses by rubbing them between the fingers. When using surfactant cleaners, please rub in the palm of hand with one finger. When in doubt – check with your Eye Care Professional.
