Alcon PRECISION7 One-Week Replacement Contact Lenses: Fresh Comfort Every 7 Days

How 1-Week Replacement Lenses Compare to Other Schedules

• Daily disposable lenses: A fresh, sterile lens every day with no cleaning required. This can be convenient and hygienic but may be more costly for some wearers when used full-time.
• Bi-weekly or monthly lenses: Lenses are reused for a longer period with appropriate cleaning and storage each day. This can be economical but requires disciplined care and may allow more time for deposits to accumulate.
• 1-week replacement lenses: A new lens every 7 days offers a middle ground for eligible patients, with regular replacement that helps limit deposit build-up while still using a reusable format.

Your optometrist will help determine which replacement schedule is most appropriate, based on your eye health, prescription, lifestyle and ability to follow a care routine.

The ACTIV-FLO System: Technology Behind PRECISION7 One-Week Replacement Lenses

One of the defining features of PRECISION7 One-week replacement lenses is the ACTIV-FLO system, described by Alcon as a sustained-release technology designed to support moisture and comfort over the full 7-day wear period. This technology is intended to help maintain a stable tear film on the lens surface, which is important for both comfort and vision quality.

In clinical studies conducted by Alcon, many wearers reported that PRECISION7 lenses provided comfortable wear and clear vision even toward the end of the replacement period, when some reusable lenses typically feel less comfortable. Although results vary from person to person, this data helps support PRECISION7 One-week replacement lenses as a suitable option for appropriate candidates.

• Designed for 7-day use before replacement, as directed by an eye care professional.
• Moisture stability on the lens surface helps support comfort during long days.
• Engineered to provide consistent vision from morning to evening throughout the week.

Any decision to wear contact lenses should always be made in consultation with an optometrist, who can evaluate whether your eyes are compatible with this type of lens and schedule.

Comfort, Vision and Digital Device Use

Many people spend a significant part of their day on digital devices. This can reduce blink rate and contribute to dryness or discomfort, especially in contact lens wearers. PRECISION7 One-week replacement lenses are designed with surface properties that help support comfort during prolonged wear, including time spent viewing screens.

In studies shared by Alcon, a high percentage of wearers agreed that PRECISION7 lenses remained comfortable during long days, including time spent on smartphones and computers. While individual experiences differ, this feedback is encouraging for patients who rely on their lenses for both work and leisure.

• Helps maintain comfort for long days, including those with extended screen time.
• Aims to support stable, clear vision from early morning to late evening.
• May be considered for patients who previously felt that their lenses dried out before the end of the day.

Who Might Be a Candidate for PRECISION7 One-Week Replacement Lenses?

Not every contact lens is suitable for every eye. A comprehensive eye examination and contact lens assessment are required before prescribing any lens. In general, PRECISION7 One-week replacement lenses may be considered for:

• Adults or suitable adolescents who need a reusable lens and prefer a simple 7-day replacement schedule.
• Patients who would like more frequent lens replacement than monthly lenses provide.
• Individuals who are motivated to follow cleaning and replacement instructions as directed.
• Wearers seeking a balance between convenience, comfort and value.

It is essential that any potential wearer be evaluated by an optometrist to confirm that the cornea, tear film and eyelids are healthy enough for contact lens wear and that the fit of the lens is appropriate.

Safety and Lens Care Essentials

All contact lenses, including PRECISION7 One-week replacement lenses, carry a risk of complications if they are not worn and cared for correctly. Following professional guidance reduces this risk and helps support healthy, comfortable wear.

• Always wash and dry your hands thoroughly before handling contact lenses.
• Use only the contact lens solutions recommended by your eye care professional.
• Follow the prescribed wear schedule and replacement frequency without extending lens use.
• Never sleep in your lenses unless your optometrist has specifically approved extended wear and provided instructions.
• Remove your lenses and contact your optometrist promptly if you experience redness, pain, light sensitivity, excessive tearing or sudden changes in vision.
• Attend regular follow-up visits to monitor your eye health and lens fit.

Your eye care professional will provide detailed instructions on how to insert, remove, clean and store your lenses, as well as how long you can safely wear them each day.
