What are Precision7® lenses?
Precision7® are weekly replacement silicone hydrogel contact lenses – meaning you open a fresh pair every Monday and wear them all week. They’re designed to deliver 16 hours of outstanding comfort and precise vision, even on day 7.
What sets them apart is Alcon’s proprietary ACTIV-FLO® System – a revolutionary 7-day sustained-release technology that continuously replenishes moisture throughout the week, keeping your eyes comfortable from first thing in the morning to last thing at night.
Why weekly lenses?
Daily disposables are often considered the gold standard, but they’re not the right fit for everyone – particularly when cost is a factor. More than half of new patients are still being fitted in reusable lenses, with 8 out of 10 choosing them due to cost.
Precision7® bridges that gap. You get a fresh lens every week, advanced silicone hydrogel technology, and a price point that works for most budgets.
What makes Precision7® different?
ACTIV-FLO® System – Precision7® has superior surface moisture stability based on 16 hours of simulated wear, outperforming leading competitors including ACUVUE OASYS 2-Week, Biofinity and Bausch + Lomb ULTRA in tear film stability testing.
Exceptional comfort ratings – 9 out of 10 wearers rated Precision7® for both comfort and vision, even on day 7.
Digital screen comfort – Significantly more Precision7® wearers agreed the lenses felt comfortable when looking at a smartphone or computer screen for extended periods, even at 16 hours of wear. Ideal for anyone spending long hours in front of screens.
Superior lens cleanliness – Precision7® contact lenses show significantly less lipid deposition versus ACUVUE OASYS 2-Week at the end of their respective replacement periods, meaning your lenses stay cleaner, clearer and more comfortable throughout the week.
Available for astigmatism – Precision7® is also available for astigmatism, featuring Alcon’s proven PRECISION BALANCE 8|4® lens design for a stable, consistent wearing experience.
