The Boston Advance Cleaner is intended for cleaning and disinfecting hard, gas-permeable lenses. Wash your hands thoroughly before touching the lenses. After wearing, remove the lenses from your eyes and clean the lenses one by one. Place the lens in the palm of your hand and apply a few drops of Boston Advance Cleaner to the lens. Gently rub the lens for 15 seconds to thoroughly clean it. Keep the lenses in fresh Boston Advance Storage and Disinfection Solution only. Never bring Boston Advance Cleaner into direct contact with the eye. If Boston Advance Cleaner accidentally gets into your eye, remove your lenses immediately and rinse your eyes with water until the cleaner is removed. Store at room temperature. Not for soft lenses. In case of eye irritation: discontinue use and consult a doctor or eye care professional.
