When it comes to prescribing daily disposable contact lenses, eyecare providers have a lot of choices. The technology behind the design can help set different lens brands apart. PRECISION1® One-Day Lenses from Alcon employ a unique water surface lens technology, designed to meet the needs of new wearers and those new to 1-day contact lenses.

In this episode, Dr. Glover interviews Dr. Christopher Lievens, OD, MS, an expert in contact lens surface technology from Memphis, Tennessee, and Dr. Erich Bauman, OD, MBA from Alcon, one of the main designers of PRECISION1®’s surface technology. They discuss the technologies that underlie these lenses, from the fascinating design of the lens water surface technology to some points about the manufacturing process. They also talk about how the technology in these lenses differs from another well-known Alcon lens, DAILIES TOTAL1®. Finally, they review some key laboratory results that compared the surface technology of PRECISION1® lenses to several competitors.This podcast is part of a 3-part series on PRECISION1® contact lenses.

UV-blocking contact lenses are NOT substitutes for protective UV-blocking eyewear such as UV-blocking goggle or sunglasses because they do not completely cover the eye and surrounding area.
