What Is the Difference Between Biofinity and AIR OPTIX Night & Day AQUA?

Biofinity and AIR OPTIX Night & Day AQUA are two prominent monthly contact lens brands, each renowned for their unique attributes and advanced lens technology.

CooperVision’s Biofinity is celebrated for its exceptional comfort and vision quality, thanks to features like Aquaform Technology and the Aberration Neutralizing System. These innovations ensure lenses stay moist and comfortable while providing crisp, clear vision. In contrast, Alcon’[s AIR OPTIX Night & Day AQUA is designed for extended wear, approved for up to 30 nights of continuous use. This brand emphasizes convenience and flexibility, making it an ideal choice for those with demanding lifestyles or for wearers who prefer the freedom of not having to remove their lenses every day.

Both products have their unique selling points, but let’s take a closer look at how they differ in terms of wearing and replacement schedules, wearing comfort, and more.

Wearing Schedule

Both Biofinity and AIR OPTIX Night & Day AQUA are FDA-approved for extended wear, but they differ in the maximum duration they can be continuously worn. Biofinity is approved for up to 6 nights of extended wear, while AIR OPTIX Night & Day AQUA stands out with its approval for up to 30 nights of continuous wear.

The extended wear feature of these lenses offers significant convenience, particularly for those with busy or unpredictable schedules. It allows wearers the freedom from daily insertion and removal routines, reducing the hassle associated with regular contact lens wear. Extended wear lenses are also beneficial for those who travel frequently or work long hours, as they eliminate the need for mid-day lens care.

AIR OPTIX Night & Day AQUA’s 30-night extended wear schedule is especially advantageous for those who require or prefer the utmost flexibility. It is designed for continuous use, making it ideal for individuals who may find daily lens maintenance challenging or inconvenient, such as shift workers or those with mobility limitations.

Replacement Schedule

Both Biofinity and AIR OPTIX Night & Day AQUA are monthly replacement lenses, which means they are designed to be replaced every 30 days. This replacement schedule offers a balance between convenience and eye health, making it a popular choice among contact lens wearers.

Monthly replacement lenses provide a more economical and environmentally friendly option compared to daily disposables. By reducing the number of lenses used and discarded over time, wearers can minimize their environmental impact. Monthly lenses can be more cost-effective in the long run, offering a full month’s wear from each pair.

The monthly replacement schedule also strikes a balance between the high maintenance of daily disposables and the potential increased risk of irritation or infection associated with extended-wear lenses. Regular monthly replacement ensures that lenses are always relatively fresh, minimizing the buildup of deposits that can cause discomfort or eye health issues.

Wearing Comfort

Wearing comfort is a key factor in the choice of contact lenses, and both Biofinity and AIR OPTIX Night & Day AQUA excel in this area, albeit with different material compositions.

Biofinity lenses are made from a silicone hydrogel material with a 48% water content. The high water content in Biofinity lenses is coupled with CooperVision’s Aquaform Technology, which locks in moisture for all-day comfort. This technology also enhances breathability, allowing more oxygen to reach the cornea. The result is a lens that feels comfortable throughout the day and promotes eye health — especially important for extended wear.

AIR OPTIX Night & Day AQUA, on the other hand, has a lower water content of 24%. While lower water content can sometimes mean less comfort due to less moisture, the silicone hydrogel material used in AIR OPTIX compensates by providing high oxygen permeability. This is particularly crucial for lenses designed for extended wear, as it helps to keep the eyes healthy and comfortable, even during continuous 30-night wear. The TriComfort Technology in AIR OPTIX Night & Day AQUA lenses further aids in retaining moisture and resisting irritating deposits, ensuring comfort from breakfast to bedtime.

Special Contact Lens Features

Both Biofinity and AIR OPTIX Night & Day AQUA come equipped with unique features that enhance their performance and wearing experience.

Biofinity boasts several special features:

  • Aquaform Technology – This technology locks in water, keeping the lenses moist and comfortable throughout the day. It also allows high levels of oxygen to reach the eyes, helping to keep them clear and white.
  • Aberration Neutralizing System – Designed to enhance vision quality by minimizing optical imperfections common in eyes, this system helps provide crisp, clear vision.
  • Smooth Rounded Edges – The lenses are designed with smooth edges to enhance comfort by minimizing interaction between the lenses and eyelids.
  • Visibility Tint – This feature aids in lens handling, making insertion and removal easier, especially for beginners and young lens wearers.

AIR OPTIX Night & Day AQUA also has its distinct features:

  • SmartShield Technology – This technology creates a protective layer of moisture that helps shield the lenses from irritating deposits.
  • TriComfort Technology – It ensures lenses stay comfortable from morning to night by allowing continuous oxygen flow, retaining moisture, and resisting irritating surface deposits.
  • Visibility Tint – Similar to Biofinity, this feature aids in the easy handling of lenses, facilitating insertion and removal.

Price Comparison

When evaluating the cost of Biofinity and AIR OPTIX Night & Day AQUA, it’s important to consider the value they provide, especially since both brands are positioned in the middle of the price spectrum for monthly lenses.

Monthly lenses like Biofinity and AIR OPTIX Night & Day AQUA offer a cost-effective alternative to daily disposables, without the higher replacement frequency. While they might have a higher initial cost compared to bi-weekly lenses, the monthly replacement schedule means fewer lenses are needed over time, translating to potential savings in the long run. The advanced features and technologies in these lenses, such as enhanced comfort and extended wear capabilities, also contribute to their overall value, making the investment worthwhile.

Customer Reviews

Customer reviews are a valuable source of insight into how Biofinity and AIR OPTIX Night & Day AQUA perform in everyday life.

Users of Biofinity often praise the lenses for their comfort, attributing this to the high water content and Aquaform Technology. Many wearers report that the lenses feel natural and keep their eyes moist throughout the day, reducing the need for rewetting drops. The value for money aspect of Biofinity is also frequently highlighted, with users appreciating the balance between quality, comfort, and affordability.

On the other hand, AIR OPTIX Night & Day AQUA receives positive reviews for its convenience and suitability for extended wear. Users who need or prefer to wear their lenses continuously find this brand particularly beneficial. The ability to wear these lenses for up to 30 nights without removal is highly valued by those with busy lifestyles or those who have trouble with daily lens maintenance. The lens’s comfort and good vision quality, despite the lower water content, are also points of satisfaction among wearers.

Brand Reputation

Exploring the reputation of CooperVision and Alcon, the manufacturers behind Biofinity and AIR OPTIX Night & Day AQUA respectively, offers additional insight into the reliability and quality of these brands.

CooperVision, the maker of Biofinity, has a long-standing reputation for producing high-quality contact lenses that focus on comfort and eye health. Known for innovative technologies like Aquaform, CooperVision has established itself as a trusted name in the contact lens industry.
