AIR OPTIX® NIGHT & DAY® AQUA contact lenses are approved for up to 30 nights of continuous wear. Before you sleep in your contact lenses, be sure to talk to your eye doctor and be honest about your sleeping habits so that you can get the contact lens that is right for you. Not everyone can sleep in lenses or wear lenses for a full 30 nights. Warning: A corneal ulcer may develop rapidly and cause eye pain, redness or blurry vision as it progresses. If left untreated, a scar, and in rare cases loss of vision, may result. The risk of serious problems is greater for extended wear vs. daily wear and smoking increases this risk
