Boston ADVANCE contact lens care multi-pack from Bausch + Lomb provides comprehensive cleaning and conditioning for rigid gas permeable (RGP) contact lenses. This value pack includes two bottles of Boston ADVANCE Conditioning Solution (4 fluid ounces each) and one bottle of Boston ADVANCE Cleaner (1 fluid ounce). The two-step care system starts with the cleaner, which loosens and removes lipids, stubborn deposits, and debris that can impair lens wearing comfort. The active ingredients include alkyl ether sulfate, ethoxylated alkyl phenol, tri-quaternary cocoa-based phospholipid, and silica gel. The cleaning solution is visibly tinted so you can see when it has been thoroughly rinsed off.

The conditioning solution is step 2 in the care system, combining disinfection with a cushioning system to soothe your eyes and provide lens wearing comfort. The disinfection system uses chlorhexidine gluconate and polyaminopropyl biguanide to kill germs on lenses, while the wetting and cushioning system features derivatized polyethylene glycol, cellulosic viscosifier, cationic cellulose derivative polymer, and polyvinyl alcohol to enhance comfortable wear by surrounding lenses with moisture. The patented multi-polymer system reduces friction against both the cornea and eyelid while removing particulate matter that may cause irritation and discomfort.

Boston is the number one eye doctor recommended brand of rigid gas permeable contact lens solutions. This system is designed for fluoro silicone acrylate and silicone acrylate rigid gas permeable lenses only, and is not for use with soft hydrophilic contact lenses. The conditioning solution is preservative-free and recommended for daily use. To use, wash hands with mild soap, rub lenses with cleaner for 20 seconds, rinse with tap water, place in empty lens case, fill with conditioning solution, and soak for at least 4 hours or overnight before wearing.
