Ciba Night & Day contacts allow up to six times more oxygen to your eyes than the leading soft lenses. The result is continuous vision that is sharp and clear, any any time of the day or night. Night & Day is FDA approved, and its breathability offers a healthy way to get more out of your contacts, and more out of life. For more information, visit nightandday.com, or talk to Dr. Stewart during your annual eye exam to see if Night & Day lenses are right for you.
