PRECISION1®
THE LENS FOR YOUR PATIENTS TO START IN AND STAY IN
PRECISION1® was born from
Water Gradient Technology
* In vitro measurement of unworn lenses.
Many new wearers struggle with contact lenses
PRECISION1® is designed to combat new lens wearer dropout
SMARTSURFACE®
Technology for
superior lens-surface
moisture stability6-9*
In in vitro studies, PRECISION1® contact lenses demonstrated superior lens-surface moisture stability vs INFUSE^, ACUVUE^ OASYS 1-DAY, Biotrue^ ONEday, 1-DAY ACUVUE^ MOIST, clariti^ 1 day and MyDay^ contact lenses.6-9*
*Based on in vitro studies wherein wettability was meastured using the iDDrop System.
All lenses were tested in an identical manner, soaked in a PBS (phosphate-buffered saline solution) for 16 hours +/- 2 hours (p<0.001).
A lens that can help new wearers transform into lifetime wearers
*Based on the mean subjective ratings on a scale of 1 (Poor) to 10 (Excellent) for overall vision, overall comfort and overall handling in subjects wearing PRECISION1® contact lenses from a clinical study, measured at three-month follow-up visit; n=105.
In a separate clinical study, PRECISION1® provided outstanding comfort even at 
Wearers rated PRECISION1® higher
than 1-DAY ACUVUE^ MOIST12
*Based on mean subjective ratings on a scale of 1 (Poor) to 10 (Excellent), from a prospective, randomized, bilateral crossover, double-masked, controlled clinical trial of PRECISION1® and 1-DAY ACUVUE^ MOIST contact lenses; p<0.0001; n=92.
Nearly 5x more wearers “strongly preferred”
PRECISION1® vs. 1-DAY ACUVUE^ MOIST13
PRECISION1® for Astigmatism
Features the proven PRECISION BALANCE 8|4® lens design for a stable contact lens wearing experience15-16
