Opti-Free Replenish Rewetting Drops are an efficient and effective solution for providing constant moisture for soft lenses, fluorosilicone acrylate lenses, and silicone acrylate gas permeable contact lenses. The rewetting drops are a safe way to prevent protein buildups on frequently used lenses.

The rewetting drops differ from many other Opti-Free solutions because they can be applied directly to the patient's eye for immediate moisture and relief, where the multi-purpose solutions are to be used strictly to soak the lens by itself.
