PRECISION1 versus DAILIES TOTAL1PRECISION1 and DAILIES TOTAL1 are two daily disposable silicone hydrogel lens manufactured by Alcon. While the lower-cost PRECISION 1 is the latest addition to Alcon's daily disposable lens portfolio, DAILIES TOTAL 1 has been available since 2013. With a different base material called Verofilcon A, PRECISION 1 belongs to the FDA Group V-B (high-water content silicone hydrogels) and comes with Class-1 UV blocking while DAILIES TOTAL 1 lacks that feature. PRECISION 1 features SMARTSURFACE® technology and DAILIES TOTAL1 is furnished with SmarTears, a technology that is stabilizing the lipid layer of the tear film. SmarTears is only available in the DAILIES TOTAL1 product line.

Let's further delve into a detailed comparison of these two lenses to help you have an informed discussion with your eye care practitioner.

Alcon, a renowned manufacturer in the contact lens industry, offers two popular options for daily disposable silicone hydrogel contact lenses: Precision1 and Dailies Total1.

Precision 1: Alcon's Newest Daily Replaceable Contacts

Introduced to the market in 2019, Precision 1 is the latest addition to Alcon's daily disposable lens portfolio. It features advanced technology and materials designed to deliver exceptional comfort and visual performance.

SMARTSURFACE Technology

Precision 1 stands out with its integration of Alcon's proprietary SMARTSURFACE® technology. This technology ensures a high water content of over 80% at the outermost surface of the lens. This unique design provides excellent hydration and moisture retention, leading to comfortable lens wear throughout the day. The SMARTSURFACE technology sets Precision1 apart, making it a top choice1 for individuals seeking superior comfort.

UV Blocking for Added Eye Protection

Another notable feature of Precision1 is its Class-1 UV blocking capability which is not available with the Dailies Total1. With more than 90% UVA and over 99% UVB protection, Precision1 shields your eyes from harmful ultraviolet rays. While not a substitute for sunglasses, this feature is especially important for individuals who spend significant time outdoors. By choosing Precision1, you can enjoy the benefits of clear vision and enhanced eye protection.

Dailies Total1: The Trusted Option

Dailies Total1, introduced by Alcon more than a decade ago, has been a trusted choice among contact lens wearers. It has gained a strong reputation for exceptional comfort and innovative technologies designed to provide a premium wearing experience.

High Oxygen Permeability

Dailies Total1 features 156 Dk/t oxygen permeability, one of the highest values in the entire soft contact lens world and much higher than what Precision 1 provides (100 Dk/t). A higher Dk/t value indicates better oxygen transmission to the cornea which can contribute to enhanced eye health, reduced dryness, and improved overall comfort throughout the day.

SmarTears Technology for Tear Film Stabilization

Dailies Total1 integrates Alcon's SmarTears Technology, which focuses on stabilizing the lipid layer of the tear film. Utilizing phosphatidylcholine (PC), SmarTears reduces water evaporation caused by lipid layer breakup. The result is a high level of moisture retention and a long tear film break-up time2 for improved comfort and reduced dryness, particularly for wearers who experience discomfort due to dry eyes. SmarTears technology is exclusive to the Dailies Total1 product line.

Smaller Range of Sphere Powers

Precision 1 offers a slightly broader range of sphere powers compared to Dailies Total1. With Precision1, you can find lenses ranging from -12.00D to +8.00D. On the other hand, Dailies Total1 provides sphere powers from -12.00D to +6.00D. So if you are extremly farsighted requiring more than +6.00D vision correction, Precision1 is a better match than Dailies Total1.

Comparing Technical Parameters

Both Precision1 and Dailies Total1 belong to the silicone hydrogel lens category. However, they differ in their specific technical parameters, including base curves, diameters, and material composition (Verofilcon A for Precision1 and Delefilcon A for Dailies Total1). These differences can impact the overall comfort, fit, and visual performance of the lenses. It's important to consult with your eye care professional to determine which parameters align with the shape and size of your cornea as well as any other individual vision requirements. Dailies Total1 is also available in toric and multifocal variations, whereas Precision1 is currently not available as a multifocal lens.

Price Comparison and Cost

When it comes to pricing, Precision1 is a much more affordable option compared to Dailies Total1, particularly in the 90 lenses per box configuration. We are monitoring more than 70 offers from the most trusted online retailers and it reveals that a full-year supply of Dailies Total1 costs around $649, while the one-year cost for Precision1 is about $467. That's a difference of $182 or close to 40% more for the Dailies Total1.
