Storing and Cleaning Contact Lenses:
Contact lenses must be stored in a suitable contact lens case, which keeps them clean, soft and safe to use. Fill the lens case with a disinfecting solution before placing the lenses inside. Make sure that they do not dry out. Never borrow another person’s contact lenses nor lend them yours. They should be handled with care, as they are very soft and delicate.
