A comparison of Air Optix Aqua and Air Optix Night and Day Aqua - two monthly replaceable lenses manufactured by Alcon Inc..

AIR OPTIX Aqua versus AIR OPTIX NIGHT and DAY AquaThe packaging was redesigned in 2017, but Air Optix Aqua was originally introduced in 2008 and Air Optix Night and Day followed in 2009. With the same silicone hydrogel material (Lotrafilcon B), an aspherical lens design, and the same wetting agents, the lenses are quite similar. However, Air Optix Night and Day are approved for an extended wearing schedule of up to 30 days. We wonder though, how many people would actually leave their lenses in for such a long period. Nevertheless, this extended wearing schedule possible because of the unique mix of materials, and the SmartShield technology (which is available in both lenses), pushing the oxygen transmission value to an astonishing 175 Dk/t. As seen in other contact lens comparisons, it's the balance of oxygen transmission and the ability to retain the water content over a long period of time, that impacts the wearing comfort. And as such the Night and Day trades oxygen transmission for a slightly lower water content. There is a bit of a price difference as you have to pay a premium for wearing the Night and Day lenses. For Air Optix Aqua the daily cost is around 44-46 cents per day. With Air Optix Night and Day this goes up to 64-66 cents.

Conclusion:

Great lenses! Both lenses come with Alcon's TriComfort and SmartShield Technology. They let up to five times more oxygen through the lens than traditional soft contact lenses and are designed to retain moisture for comfort all day long. Plus they have superior deposit resistance for cleaner lenses. The higher priced Air Optix Night & Day has one of the highest Dk/t values, which might result in some additional wearing comfort.  Prescription parameters are different (diameter and base curve), and Air Optix Night and Day Aqua was approved by the FDA for daily wear and extended wear for up to 30 nights of continuous wear.
