Alcon’s PRECISION7 contact lenses offer a different approach to reusable contacts with a convenient seven-day replacement schedule. Made from breathable silicone hydrogel material, these lenses feature the ACTIV-FLO System, a technology designed to maintain moisture and support comfortable wear throughout the week. They’re available as standard PRECISION7 Contact Lenses and PRECISION7 for Astigmatism Contact Lenses for people who need toric vision correction.
But what makes PRECISION7 different from other contact lenses, and how does its technology work? This guide takes a closer look at its features, seven-day benefits, available options, and proper care to help you understand what to expect from these weekly lenses.
Takeaways
- PRECISION7 contact lenses are made from breathable silicone hydrogel material and are designed to be replaced every seven days, offering an alternative to daily and monthly contacts.
- Alcon’s ACTIV-FLO System combines moisturizing and replenishing agents to help maintain lens hydration and comfortable wear for up to 16 hours a day, even on day seven.
- PRECISION7 corrects nearsightedness and farsightedness, while PRECISION7 for Astigmatism features PRECISION BALANCE 8|4 lens design to help maintain stable vision.
- PRECISION7 lenses feature Class 1 UV protection and blue-violet light filtering, although they don’t replace UV-protective sunglasses.
- PRECISION7 lenses require regular cleaning and disinfection when used for daily wear. An eye care professional can determine the appropriate prescription, fit, and wearing schedule.
What Are PRECISION7 Contact Lenses?
PRECISION7 contact lenses are weekly replacement lenses developed by Alcon, a global eye care company. They’re made from serafilcon A, a silicone hydrogel material that lets oxygen pass through the lens to the cornea while helping maintain a comfortable fit. These soft contact lenses are designed to correct common vision problems, including nearsightedness and farsightedness, with a separate toric version available for astigmatism.
Unlike daily disposable contacts that you throw away after each use or monthly lenses that you replace after about 30 days, PRECISION7 follows a seven-day replacement schedule. You wear the lenses during the day, remove and properly disinfect them as directed, and start with a fresh pair every week. This gives wearers a shorter replacement cycle without needing a new pair every morning.
PRECISION7 is designed for people who prefer reusable contacts but want a more frequent replacement schedule. Its breathable material, moisture-focused design, and weekly replacement cycle make it an option for those looking for a balance of comfort, convenience, and consistent vision throughout their wearing week.
How Does PRECISION7’s ACTIV-FLO Technology Work?
What sets PRECISION7 apart is Alcon’s ACTIV-FLO System, a moisture-focused technology designed to keep the lens surface hydrated throughout its seven-day replacement cycle. Unlike lens technologies that rely mainly on surface treatments, ACTIV-FLO combines two moisturizing components that work together to maintain moisture as the lens is worn.
The first is a water-loving moisturizing agent permanently embedded in the lens material. It helps the lens attract and retain water, keeping its surface wettable. The second is a replenishing agent stored within the lens that gradually moves to the surface, providing a continuous supply of moisture. This release begins once the lens is removed from its packaging solution and continues throughout the week.
Together, these components help PRECISION7 maintain surface moisture from day one through day seven, rather than relying only on the moisture present when the lens is first inserted. According to Alcon, the technology supports up to 16 hours of comfortable wear each day, including the final day of the weekly replacement cycle.
What Are the Benefits of PRECISION7 Contact Lenses?
Beyond its moisture-retaining technology, PRECISION7 offers several practical benefits for people who wear contacts regularly. From lasting comfort to built-in light filtering, these lenses are designed to support clear vision and fit into everyday routines without requiring a fresh pair each morning.
Consistent Comfort Throughout the Week
PRECISION7 is designed to deliver up to 16 hours of comfortable wear each day, including the seventh day of its replacement cycle. Its moisture-focused design helps the lens surface remain wettable during long days, whether you’re working, studying, or spending time on digital devices.
In Alcon’s clinical study, wearers rated PRECISION7 an average of 9 out of 10 for comfort, even on day seven. The lenses also demonstrated resistance to lipid deposits in laboratory testing, which can help maintain a cleaner lens surface throughout the wearing week.
Clear and Stable Vision
PRECISION7 lenses are designed to maintain consistent visual performance from the beginning to the end of the week. Their silicone hydrogel material supports oxygen transmission to the cornea, while the lens design provides the optical correction prescribed for each wearer.
Alcon’s clinical findings showed an average vision rating of 9 out of 10 on the seventh day. This makes PRECISION7 an option for people who want dependable vision during everyday activities without switching to a fresh pair daily.
Convenient Seven-Day Replacement Schedule
One of PRECISION7’s most practical advantages is its weekly replacement schedule. Instead of opening a new pair every morning or keeping the same lenses for an entire month, you replace them on the same day each week.
Choosing a regular replacement day makes the schedule easier to remember, especially for people who are new to reusable contacts. You’ll still need to follow the prescribed cleaning and storage routine between uses, but the shorter replacement cycle offers a convenient alternative to traditional monthly lenses.
UV Protection and Blue-Violet Light Filtering
PRECISION7 also includes built-in light-filtering features. Its Class 1 UV protection helps absorb ultraviolet radiation, while its blue-violet light filter reduces the amount of certain short-wavelength visible light passing through the lens.
According to Alcon’s product specifications, here’s how much light PRECISION7 filters:
| Light type | Filtering performance |
|---|---|
| UVA rays | More than 90% blocked |
| UVB rays | More than 99% blocked |
| Blue-violet light | 34% filtered |
Although UV-blocking contacts offer additional protection, they don’t cover the entire eye or surrounding skin. Sunglasses with UV protection are still recommended when spending time outdoors. It’s also worth noting that blue-violet light filtering hasn’t been proven to reduce digital eye strain or prevent eye disease.
Are PRECISION7 Contact Lenses Available for Astigmatism?
Yes, Alcon offers PRECISION7 for Astigmatism, also known as PRECISION7 toric contact lenses, for people with astigmatism. Like the standard version, these lenses use serafilcon A silicone hydrogel material and the ACTIV-FLO System to support comfortable wear throughout the seven-day replacement cycle. However, the toric version also features Alcon’s PRECISION BALANCE 8|4 lens design, which uses stabilization points at the 8 and 4 o’clock positions to help prevent unwanted lens rotation. According to Alcon, this design helps the lens settle into position in less than 60 seconds and maintain stable vision during blinking.
The main difference between the two versions is the type of vision correction they offer. Standard PRECISION7 lenses correct nearsightedness or farsightedness, while PRECISION7 for Astigmatism also corrects blurry or distorted vision caused by astigmatism. Both follow the same weekly replacement schedule and share the same moisture-focused technology, but the toric version includes cylinder and axis measurements to address astigmatism. Your eye care professional can determine which option best suits your prescription and vision needs.
How Does PRECISION7 Compare to Other Contact Lenses?
PRECISION7 offers a middle ground between daily disposable and monthly contact lenses. The main differences come down to replacement schedules, maintenance, and personal preferences.
PRECISION7 vs. PRECISION1
Both lenses are made by Alcon, but PRECISION1 is a daily disposable lens featuring SMARTSURFACE Technology, while PRECISION7 uses the ACTIV-FLO System and follows a weekly replacement schedule. PRECISION1 requires no cleaning or storage, whereas PRECISION7 is reusable and requires proper care between uses.
PRECISION7 vs. Monthly Contact Lenses
PRECISION7 lenses are replaced every seven days, compared to approximately 30 days for monthly contacts. Both require cleaning and storage when worn on a daily-wear schedule. PRECISION7 suits people who prefer more frequent replacements, while monthly lenses offer a longer replacement cycle with fewer new pairs needed throughout the year.
Who Should Wear PRECISION7 Contact Lenses and How Do You Care for Them?
PRECISION7 contact lenses are worth considering for people who prefer reusable contacts with a shorter replacement cycle. They’re designed for those seeking comfortable vision throughout the week without opening a fresh pair every day. However, an eye examination and professional fitting are necessary to determine whether these lenses suit your prescription and eye health.
For daily wear, proper care helps keep your PRECISION7 lenses clean and safe throughout their seven-day replacement cycle. Follow these basic guidelines:
| Contact Lens Care Tips |
|---|
| Wash and dry your hands before handling your lenses. |
| Remove, clean, and disinfect your lenses using the recommended contact lens solution after each day of wear. |
| Store your lenses in a clean case with fresh disinfecting solution. Avoid water or reusing old solution. |
| Replace your lenses every seven days, even when they still feel comfortable. |
| Avoid sleeping in your lenses unless your eye care professional specifically approves overnight wear. |
Although PRECISION7 is approved for certain extended-wear schedules, sleeping in contacts increases the risk of eye infections. Always follow your eye care professional’s prescribed wearing schedule and care instructions.
Are PRECISION7 Contact Lenses Right for You?
PRECISION7 contact lenses offer a convenient alternative to daily and monthly lenses, combining Alcon’s ACTIV-FLO System with a seven-day replacement schedule.
