The market for daily disposable contact lenses is dominated by the four major contact lens manufacturers Alcon, Bausch and Lomb, Johnson and Johnson, and CooperVision. Together they offer about ten different daily disposable lenses for the correction of near/far-sightedness. They were all introduced in the last 12 years, with Soflens Dailies being the oldest, and ACUVUE OASYS 1-DAY being the most recent lens added in 2016.
DAILIES TOTAL1 (2013) and Clariti 1 Day (2009) are silicone hydrogel lenses with a daily replacement modality. While DAILIES TOTAL1 is a spherical lens, CooperVision applied an aspherical lens design to the Clariti product line. Center thickness and modulus are similar, but the big difference is in the water content and the ability to let oxygen pass through the lens. When you look at the water content you will notice a 56% value for Clariti 1-Day compared to a 33% value for DAILIES TOTAL1. Due to the high water content, Coopervision's Clariti lens doesn't require an additional wetting agent. In contrast, DAILIES TOTAL1's ability to let oxygen through to your eyes manifests in a 156Dk/t value compared to the 86Dk/t value we noticed in the Clariti 1-Day. We have seen this in other lens comparisons and it comes down to finding the right balance between oxygen flow to the cornea and the ability to retain water throughout the day. What is more important? The answer: It depends on your eyes. Some people prefer a more moist lens, some people prefer a more breathable lens. So in case you have a chance to get into a trial with both lenses, the reaction of your eyes with one lens over the other could be quite different. If your eye care practitioner prescribes the DAILIES TOTAL1, expect a 20% higher ticket price when compared to the daily cost of Clariti 1-Day.
