Boston Advance Formula Conditioning Solution features an advanced comfort formula that is useful for wetting, soaking, and disinfecting rigid gas permeable and hard contact lenses. This solution helps remove protein deposits and debris, ensuring lenses stay clean and comfortable throughout the day. It also conditions and wets lenses, promoting a comfortable and moist lens-wearing experience. Ingredients include Cationic Cellulose Derivative Polymer, Cellulosic Viscosifier, Polyvinyl Alcohol & a derivatised Polyethylene Glycol as wetting & cushioning agents. It is preserved with Chlorhexidine Gluconate (0.003%), Polyaminopropyl Biguanide (0.0005%), and Edetate Disodium (0.05%). Keep out of reach of children. Do not use if allergic to any ingredients. Solution can irritate eyes unless removed by thorough rinsing. If solution contacts eyes, remove lenses and flush eyes with fresh tap water. Always use fresh solution for soaking and storing lenses at room temperature. Wash hands with mild soap before use. After cleaning with Boston Advance Cleaner and rinsing, place lenses in an empty lens case filled with fresh solution. Soak for at least 4 hours or overnight. Apply fresh solution to wet lenses for additional cushioning if desired before inserting.
