PRECISION1 versus 1-DAY ACUVUE MOIST - a ComparisonIt's August 2019 and Alcon just announced the release of PRECISION1 in the US. It had already been introduced in Australia and New Zealand. Alcon is rolling it out through select eye care practitioners in the US followed by a roll-out to many countries around the world in 2020. Alcon's latest daily disposable silicone hydrogel features SMARTSURFACE Technology, promising a significant increase in wearing comfort. A clinical study showed an advantage over 1-DAY ACUVUE® MOIST in end-of-day vision, end-of-day comfort, and overall handling.

A direct comparison of the technical parameters of PRECISION1 and 1-DAY ACUVUE® MOIST uncovers the following similarities and differences:

PRECISION1 is a silicone hydrogel contact lens with a 51% water content in the core which gets boosted to 80% at the lens surface. 1-DAY ACUVUE® MOIST is made with Etalfilcon A, an ionic hydrogel material with a 58% water content. Besides the difference in surface water content, it is the ability to let oxygen pass through to the eye, that is quite different. PRECISION1's oxygen transmission value is above the 100 marks, compared to the 33Dk/t value seen in the 1-DAY ACUVUE® MOIST lens. This is not a surprise, considering the superior oxygen transmission capabilities of silicone hydrogel lenses in general. After all, this is one of the main reasons why this (silicone hydrogel) material got so popular and is considered the material-of-choice by many soft contact lens manufacturers.
Both lenses feature UV blocking; PRECISION1 got classified as a Class-1 UV blocking lens, while 1-DAY ACUVUE® MOIST provides Class-2 UV blocking. It's good to see that Alcon is adding UVA and UVB blocking to their silicone hydrogel daily disposable lens portfolio - something not available in the DAILIES TOTAL1 lenses.
