Detailed Description
There is a paucity of data on the wear experience of DAILIES TOTAL1 Multifocal contact lenses in a population that has previously worn INFUSE One-Day Multifocal. While existing multifocal lenses provide adequate refractive correction, they often fail to maintain the complex biochemical homeostasis of the aging tear film, leading to significant "end-of-day" discomfort and fluctuating vision as the lens surface dehydrates. There remains a critical clinical need for a lens material that doesn't simply offer physical lubrication, but actively mimics the eye's natural environment-either through a high-oxygen water gradient surface to minimize mechanical friction or the infusion of osmoprotectants and electrolytes to prevent hyperosmotic stress. This study addresses the gap in providing a sustainable, all-day wearing experience that preserves both physiological health and the precise optical clarity required for multifocal success.
