PRECISION1 for Astigmatism by Alcon offers a high-performance solution for those requiring sharp, stable vision combined with the effortless convenience of a daily disposable lens. These lenses are designed to correct astigmatism—often in conjunction with myopia (short-sightedness) or hyperopia (long-sightedness)—by providing a stable and comfortable fit that lasts all day.
Also available in a PRECISION1 for Astigmatism 30 Pack.
The Clinical Innovation of SMARTSURFACE® Technology
The hallmark of PRECISION1 for Astigmatism is SMARTSURFACE® Technology. This micro-thin layer of moisture permanently supports the lens surface, raising the water content from 51% at the core to over 80% at the outermost surface. This gradient creates a long-lasting cushion of hydration that significantly reduces friction between the lens and the eyelid, ensuring comfort that lasts from morning until late at night.
Visual Stability with PRECISION BALANCE 8|4® Design
To deliver consistent clarity for astigmatic patients, Alcon Precision 1 toric lenses utilize the PRECISION BALANCE 8|4® Design. This dual-zone stabilization system leverages the natural blinking motion of the eye to ensure the lens settles quickly and remains perfectly aligned. By preventing the rotational blur that often plagues astigmatism correction, these daily astigmatism lenses provide reliable, uninterrupted vision for even the most active wearers.
Breathable Silicone Hydrogel and UV Protection
Constructed from Verofilcon A, a modern silicone hydrogel material, these lenses provide an oxygen transmissibility of 90 Dk/t. This high level of breathability supports healthy corneal oxygen consumption, helping to prevent the end-of-day redness often seen with older lens types. Furthermore, the integrated Class 1 UV protection blocks over 90% of UVA and 99% of UVB rays, offering a supplemental layer of ocular defense against harmful solar radiation.
Who Should Consider PRECISION1 for Astigmatism?
Optometrists frequently recommend PRECISION1 for Astigmatism for patients who:
- Require a reliable daily disposable lens to correct astigmatism (toric prescription).
- Experience lens awareness or end-of-day dryness with traditional hydrogel lenses.
- Lead active lifestyles where the hygiene and simplicity of a daily disposable lens are preferred.
Note: Suitability, fit, and replacement schedules must always be confirmed by your optometrist.

Common Questions About PRECISION1 for Astigmatism
Can I wear PRECISION1 for Astigmatism lenses overnight?
No, PRECISION1 for Astigmatism is strictly designed for daily wear. While the Verofilcon A material is highly breathable, the lenses must be removed and discarded each night to maintain optimal eye health and prevent the risk of severe corneal hypoxia or infection.
What is the difference between PRECISION1 for Astigmatism and Dailies TOTAL1 for Astigmatism?
Both are premium toric lenses from Alcon, but they feature different moisture technologies. PRECISION1 for Astigmatism uses SMARTSURFACE® Technology (>80% surface water) as a high-performance mainstream option. Dailies TOTAL1 for Astigmatism features Water Gradient Technology, which approaches nearly 100% water at the surface, designed for patients requiring the highest possible level of moisture retention.
How does the stabilization system work in Alcon Precision 1 toric lenses?
Visual clarity is maintained through the PRECISION BALANCE 8|4® Design. This system uses the pressure from your eyelids during a blink to quickly orient the lens and hold it securely in place. This prevents the lens from rotating out of position, ensuring your vision remains focused and free from blur throughout the day.
