OptiFree Pure Moist is designed specifically to provide all-day comfort by moisturizing the lens.
On the other hand, OptiFree Pure Moist uses a multi-action disinfectant system to effectively remove bacteria and other harmful particles from the lens. The solution requires only 5 minutes of soaking time, making it a convenient option for individuals who are short on time. The hydrogen peroxide in OptiFree Replenish is the disinfecting agent and requires a soaking time of 6 hours.
