Disclaimer: These contact lenses are available by prescription only for vision correction. An eye doctor will determine whether contact lenses are right for you. Although rare, serious eye problems can develop while wearing contact lenses. To help avoid these problems, follow the wear and replacement schedule and the lens care instructions provided by your eye doctor. Do not wear contact lenses if you have an eye infection, or experience eye discomfort, excessive tearing, vision changes, redness or other eye problems. Overnight wear of contact lenses has been shown to increase the risk of serious contact lens-related complications. Do not wear contact lenses overnight or on a continuous basis (24 hours a day, including during sleep) unless prescribed by your eye care professional.
