Product Introduction
Air Optix Night and Day contact lenses are a high-performance monthly solution designed by Alcon for patients who require the clinical flexibility of continuous extended wear. Engineered with the highest oxygen transmissibility of any soft lens, they are a primary choice for those with demanding lifestyles, including shift workers and frequent travellers, who need reliable vision without the necessity of daily removal.
Maximising Ocular Health with Air Optix Night and Day Continuous Wear
These Alcon monthly lenses are manufactured using Lotrafilcon A, a specialized silicone hydrogel material that delivers an exceptional oxygen transmissibility of 175 Dk/t. This industry-leading breathability allows the cornea to receive near-unrestricted oxygen flow, which is critical for maintaining clear, white, and healthy-looking eyes during long-wearing periods and overnight use.
To ensure consistent clarity across the full 30-day replacement cycle, Air Optix Night and Day features SmartShield® Technology. This ultra-thin protective layer creates a permanent barrier that resists the adhesion of lipid deposits and cosmetic residues, preventing the surface irritation often associated with monthly wear. Furthermore, the integrated Aqua Wetting System works to minimise lens-lid interaction, providing a smooth and comfortable experience from the first hour to the end of the month.
Who Should Wear Air Optix Night and Day?
While a reliable option for general myopia (short-sightedness) and hyperopia (long-sightedness) correction, Air Optix Night and Day is specifically engineered for wearers who require a lens that can keep up with an irregular or active schedule. It is often recommended for patients who:
- Require the clinical option of continuous wear for up to 30 nights, subject to professional approval.
- Experience end-of-day redness or dryness caused by low oxygen transmission in standard lenses.
- Have occupations or lifestyles that make daily lens care impractical, such as emergency responders or frequent flyers.
Note: Suitability, fit, and replacement schedules must always be confirmed by your optometrist.

Common Questions About Air Optix Night and Day
Is it safe to sleep in Air Optix Night and Day contact lenses?
Air Optix Night and Day is FDA-approved for up to 30 nights of continuous wear. However, because overnight wear carries an increased clinical risk of infection, any extended wear schedule must be explicitly approved and monitored by an optometrist to ensure it is suitable for your specific ocular health.
How does Air Optix Night and Day compare to Air Optix plus HydraGlyde?
Air Optix Night and Day is primarily engineered for maximum oxygen delivery (175 Dk/t) to support long-term overnight wear. In contrast, Air Optix plus HydraGlyde is tailored for daily wear comfort using the HydraGlyde Moisture Matrix, although it remains approved for shorter extended wear periods of up to six nights.
Are Air Optix Night and Day lenses suitable for dry eyes?
Many patients with mild dryness find these lenses well-tolerated. The Lotrafilcon A material features a low water content of 24%, meaning the lens is less likely to draw moisture away from the eye's natural tear film, helping to maintain comfort in dry or air-conditioned environments.
