When cared for properly, contact lenses can provide a comfortable and convenient way to work, play, and live for the 30 million plus people in the U.S. who wear them. While contact lenses are usually a safe and effective form of vision correction, they are not entirely risk-free—especially if they are not cared for properly. Contact lenses are medical devices, and failure to wear, clean, and store them as directed can increase the risk of eye infections, such as microbial keratitis. To reap the benefits of wearing contact lenses, it is essential to practice healthy habits. Remember: Healthy Habits = Healthy Eyes.
