PRECISION7 for Astigmatism 12 Pack
$96.48
PRECISION7 for Astigmatism are reusable toric contact lenses with a one-week replacement schedule. Their defining feature is Alcon’s ACTIV-FLO system, which gradually releases a wetting agent from the serafilcon A lens material throughout the seven-day cycle. PRECISION BALANCE 8|4 design helps the astigmatism-correcting optics settle in the intended position. Each lens has 55% water content, Class 1 UV absorption, an 8.6 mm base curve, and a 14.5 mm diameter. Remove, clean, disinfect, and store the lenses each night, then replace them with a fresh pair every week as directed by your eye care professional.
A Weekly Toric Lens with a Seven-Day Moisture System
PRECISION7 for Astigmatism is an Alcon toric contact lens for people whose prescription includes astigmatism together with nearsightedness or farsightedness. Instead of a daily or monthly schedule, this reusable lens is replaced every seven days. ACTIV-FLO technology is built into the serafilcon A material and releases a wetting agent over the course of the week to support surface moisture through the intended replacement cycle. The optical design is equally product-specific: PRECISION BALANCE 8|4 uses stabilization points positioned around the lower portion of the lens to help its cylinder and axis correction settle in the prescribed orientation.
How ACTIV-FLO and the Toric Design Work
Serafilcon A is a silicone hydrogel material with 55% core water content. The toric lens has an oxygen transmissibility of 119 Dk/t at -3.00D. ACTIV-FLO is a sustained-release system in which water-attracting components within the lens matrix move toward the surface over the seven-day replacement period. In manufacturer studies, the design was evaluated through 16 hours of wear on day seven; individual wearing time should still follow the schedule prescribed by an eye care professional.
Astigmatism correction requires the lens to maintain the correct rotational position. PRECISION BALANCE 8|4 places stabilization areas at approximately the 8 and 4 o’clock positions to reduce interaction with the lower eyelid. A single mark at 6 o’clock gives the fitter an orientation reference. Alcon reports that the design settles quickly and shows little movement with blinking, but the prescription still needs to be professionally fitted for the wearer’s eye.
This model filters 34% of blue-violet light and meets Alcon’s Class 1 UV absorption specification, filtering more than 90% of UVA and 99% of UVB rays. Blue-violet filtering has not been demonstrated to provide health benefits such as reduced eye strain or retinal protection. A UV-absorbing contact lens also covers only part of the eye, so sunglasses or other UV-protective eyewear are still needed as directed.

- PRECISION BALANCE 8|4 design: Stabilization points at 8 and 4 o’clock support orientation, with a 6 o’clock fitting mark.
- Serafilcon A silicone hydrogel: The material has 55% core water content and a toric Dk/t of 119 at -3.00D.
- Class 1 UV absorption: The lens filters more than 90% of UVA and 99% of UVB rays but does not replace sunglasses.
- Retail pack size: This listing contains 12 lenses with one parameter combination per box.
Who Are These Weekly Toric Contacts For?
This lens is intended for people prescribed toric correction for myopia or hyperopia with astigmatism. It may be relevant to established wearers who use this exact model and prefer a clearly defined weekly change day. Unlike a daily disposable, it requires cleaning, disinfection, and storage after each day of wear.
The combination of power, cylinder, axis, base curve, diameter, material, and toric geometry is specific to PRECISION7 for Astigmatism. A prescription for another Alcon lens—or another toric brand—should not be converted without an eye care professional. This model is not multifocal and does not include an ADD parameter.

Buying PRECISION7 for Astigmatism Online
Match the product to a valid prescription for this exact model and check the power, cylinder, and axis for each eye. One box contains a single parameter combination, so different right- and left-eye prescriptions require separate boxes. This listing contains 12 lenses with one power, cylinder, and axis combination.
Frequently Asked Questions
Are PRECISION7 for Astigmatism lenses daily or weekly?
They are reusable lenses replaced every week, not daily disposables or monthly lenses. During the seven-day cycle, remove them before bed, then clean, disinfect, and store them in fresh contact lens solution. Start a new pair after one week, or follow a different wearing instruction only if it was specifically provided by your eye care professional.
What does PRECISION7 for Astigmatism correct?This toric model corrects myopia or hyperopia in people who also have astigmatism. It uses power, cylinder, and axis parameters, and its PRECISION BALANCE 8|4 design helps position the astigmatism correction. It is not a multifocal lens and does not include an ADD value for presbyopia.
How many PRECISION7 for Astigmatism lenses are in a box?This retail box contains 12 lenses. Every lens in the box has the same power, cylinder, and axis, so separate boxes are usually required when the two eyes have different parameters. Every lens within one retail box has the same power, cylinder, and axis, so separate boxes are usually required when the two eyes have different parameters.
What base curve and diameter do these contacts use?PRECISION7 for Astigmatism has one listed base curve of 8.6 mm and a diameter of 14.5 mm. Those measurements are part of the complete toric lens design and do not make it interchangeable with another product that happens to show similar numbers. Order the exact brand and parameters written on the prescription.
Do PRECISION7 for Astigmatism lenses have UV protection?They provide Class 1 UV absorption, filtering more than 90% of UVA and 99% of UVB rays. They also filter 34% of blue-violet light. Contact lenses do not cover the entire eye or surrounding area, so this feature does not replace UV-blocking sunglasses. Alcon does not claim a demonstrated health benefit from the blue-violet light filtration.
Availability and lead time depend on the prescription parameters. Some configurations are supplied to us from the manufacturer. Estimated shipping time is up to 5 business days.
