NaturalVue® (etafilcon A) Brand Contact Lenses are available by prescription only for vision correction. An Eye Care Professional will determine whether contact lenses are right for you. Follow the wear and replacement schedule and the lens care instructions provided by your Eye Care Professional. Although rare, serious eye problems can develop while wearing contact lenses. Therefore, it is important to talk to your Eye Care Professional about proper wear and care of your lenses. Only your Eye Care Professional can determine if contact lenses are right for you. If your Eye Care Professional has prescribed contact lenses for you, you should not wear them if you have an eye infection, or experience eye discomfort, excessive tearing, vision changes, redness or other eye problems. If one of these conditions occurs, contact your Eye Care Professional immediately.
