Product Description Air Optix Night & Day Aqua contact lenses by Alcon & Ciba Vision are monthly disposable extended wear contact lenses. They can be worn for up to 30 days and 30 nights without requiring removal, if approved by your optician. Air Optix Night & Day feature exclusive TriComfort technology for a smooth, moist, and deposit resistant lens. This helps them to keep eyes hydrated around the clock as well as ensuring a highly breathable lens, allowing oxygen to reach the eyes for optimal eye health. As silicone hydrogel contact lenses, they allow up to six times the amount of oxygen to travel through to your eyes than standard hydrogel lenses. We also stock Air Optix Night & Day Aqua contact lenses in a larger 6 pack supply. Please check with your optician before trying these contact lenses to find out if extended wear lenses are suitable for your eyes. Need more optical advice help? Ask our optical experts
