Precision1® for Astigmatism 90 Pack

Each box of Precision1 for Astigmatism 90 Pack contains 90 individually packaged daily disposable toric lenses. Since each lens is worn once and discarded, 90 lenses provides a three-month supply for both eyes — 45 lenses per eye.

Precision1 for Astigmatism lenses are daily disposables. Each lens is worn once and discarded at the end of the day. No cleaning, rinsing, or storage solution is required. The 90 Pack refers to the quantity in the box — not a monthly replacement schedule.

Precision1 for Astigmatism lenses are made from Verofilcon A, a silicone hydrogel material with 51% core water content and an oxygen permeability of 90 Dk/t. The lens has a base curve of 8.5 mm and a diameter of 14.5 mm. Verofilcon A serves as the lens core, while SMARTSURFACE® Technology provides a permanent moisture layer with over 80% water content at the surface.

SMARTSURFACE® Technology is Alcon's proprietary water gradient surface system found in every Precision1 lens. It creates a permanent micro-thin moisture layer — measuring 2 to 4 microns — that is chemically anchored to the outer lens surface. This layer maintains over 80% water content at the lens surface throughout the day, providing consistent comfort from insertion to end of day without relying on a removable coating that can wear off over time.

PRECISION BALANCE 8|4® Design is Alcon's toric lens stabilization system. It uses optimized lens geometry at the 8 o'clock and 4 o'clock positions to work with the natural blink action of the eyelids, keeping the lens correctly oriented on the eye. This allows the lens to stabilize within approximately 60 seconds of insertion and recover quickly from any movement caused by blinking or eye movement — providing the rotational stability that accurate astigmatism correction requires.

Yes. Precision1 for Astigmatism lenses carry Class 1 UV protection — the highest UV blocking classification available in contact lenses — filtering up to 90% of UVA rays and 99% of UVB rays. This makes them well-suited for wearers in high UV environments such as beaches, mountains, or snowy conditions. However, contact lenses do not cover the entire eye and surrounding area — UV-protective sunglasses are still recommended for comprehensive outdoor protection.

Yes. Toric contact lenses for astigmatism require a more complex design than standard sphere lenses, incorporating cylinder power and axis parameters in addition to sphere correction. This added manufacturing complexity generally results in a higher price point. Daily disposable toric lenses like Precision1 for Astigmatism may cost more per box than sphere dailies, but the convenience of no cleaning or storage can offset some of the overall cost.

Astigmatism is corrected using toric contact lenses. Unlike standard sphere lenses, toric lenses have different refractive powers on their vertical and horizontal meridians to compensate for the uneven curvature of the cornea or lens that causes astigmatism. They also include a stabilization design to keep the lens correctly oriented on the eye, which is essential for consistent astigmatism correction.

Precision1 for Astigmatism lenses correct astigmatism using a toric optical design with PRECISION BALANCE 8|4® Design for lens stabilization. The toric geometry provides different corrective powers at different meridians of the lens to compensate for the irregular curvature causing the astigmatism, while PRECISION BALANCE 8|4® keeps the lens correctly oriented throughout the day. SMARTSURFACE® Technology maintains a moisture-rich lens surface for consistent visual clarity and all-day comfort.

Yes. Precision1 for Astigmatism lenses use SMARTSURFACE® Technology to maintain over 80% water content at the lens surface throughout the day. This provides consistent surface moisture and supports a stable tear film, contributing to all-day comfort. The daily disposable format also means a fresh, preservative-free lens every day, which many wearers find reduces end-of-day lens awareness.

Precision1 for Astigmatism lenses are designed for daily disposable use — one day of wear per lens. Remove and discard them at the end of each day. Do not reuse or store overnight. Always follow the wear schedule recommended by your eye care professional.

No. Precision1 for Astigmatism lenses are approved for daily wear only and should be removed and discarded before sleeping. If you require extended or overnight wear options, consult your eye care professional for appropriate alternatives.

It is not recommended to wear contact lenses while swimming or showering. Water — including pools, lakes, oceans, and tap water — can harbor microorganisms that may cause serious eye infection. If lenses come into contact with water, remove and discard them immediately. Consult your eye care professional for guidance on prescription eyewear for water activities.

Precision1 for Astigmatism lenses may be suitable for individuals with eye allergies. As daily disposables, a fresh lens each day means no accumulated allergens or deposits from previous wear — which many allergy-prone wearers find beneficial compared to reusable lenses. Consult your eye care professional for personalized advice on whether daily disposable toric lenses are appropriate for your specific allergy and vision needs.

If you experience eye irritation while wearing Precision1 for Astigmatism lenses, remove the lenses immediately and consult your eye care professional for an evaluation. Do not reinsert the same lens. If irritation persists after lens removal, seek professional guidance promptly.

Yes. A valid prescription from a licensed eye care professional is required. Toric lenses require specific parameters beyond standard sphere lenses — including cylinder power and axis — making a current, accurate prescription essential for correct fit and effective astigmatism correction.

A single box provides a three-month supply for both eyes with daily wear. Two boxes are recommended for a six-month supply. Four boxes total are needed for a full year's supply.

The Precision1 for Astigmatism 30 Pack is ideal for first-time wearers trying the lens for the first time. The 90 Pack offers better per-lens value for established wearers who already know the lens suits their eyes, providing a full three-month supply in a single purchase and reducing reorder frequency.

Both are premium daily disposable toric lenses but from different manufacturers with different technologies. Precision1 for Astigmatism uses Verofilcon A with SMARTSURFACE® Technology and PRECISION BALANCE 8|4® Design, with Class 1 UV protection. MyDay Toric from CooperVision uses Stenfilcon A with Smart Silicone Technology and Aquaform Technology for moisture retention. Both offer stable toric vision — your eye care professional can help determine which fits your prescription and eye shape best.

Both share the same Verofilcon A material, SMARTSURFACE® Technology, Class 1 UV protection, and daily disposable format. The key difference is lens design. The standard Precision1 sphere corrects nearsightedness and farsightedness only. Precision1 for Astigmatism adds PRECISION BALANCE 8|4® toric geometry for cylinder and axis correction. If your prescription includes cylinder and axis values, a toric lens like Precision1 for Astigmatism is required.
