Wash and dry your hands thoroughly before handling the lenses. Clean, disinfect and store reusable lenses with an appropriate contact lens care solution. Avoid exposing the lenses to water and never use water or saliva for cleaning or storage. Do not share lenses with another person. Remove them before sleeping unless your eye care professional specifically advises otherwise. Follow the replacement schedule printed on the original product packaging and the instructions of your eye care professional because the replacement period differs between available sources. If pain, persistent redness, irritation or an unusual change in vision occurs, remove the lenses and seek professional advice before wearing them again.
