New times need new technologies: Alcon's contact lenses with a high water content on the surface set a new material standard. Find out more about Alcon's water surface lenses.
Contact lens technology has undergone a remarkable evolution over the past 50 years. 1] Nevertheless, one in two contact lens wearers still regularly experiences discomfort and about one in three contact lens wearers stops wearing lenses permanently for this reason. 2–5]
These complaints often result from the use of older lens technologies that are not designed for modern requirements such as working at computer screens and environmental influences.
To counteract this, Alcon has developed contact lenses with a high water content on the surface that set a new material standard and revolutionize comfort.
DAILIES TOTAL1® and TOTAL30® are made of almost 100% water at the surface* and provide high lubricity[**/***], which significantly improves comfort while wearing them.[6-12]
PRECISION1™ contact lenses have a water content of over 80% at the surface and offer your customers long-lasting comfort, even after 16 hours. [13-16]
If you have any questions or require further information, please do not hesitate to contact your Alcon representative.

*Other proprietary wetting agents or other surface treatments may be used to enhance wettability, softness and comfort. Based on critical friction coefficient measured using the nano-tribometer (“worn” spherical lenses were worn on the eye for one full wear cycle: 14 days for ACUVUE OASYS^, 30 days for Biofinity^, ACUVUE V ITA^, Bausch+Lomb ULTRA^); p<0.05. ***Contact lenses were placed on a membrane-covered probe and pushed over living eye epithelial cells for 1,000 cycles with forces that mimic typical eye pressure. The coefficient of friction was calculated for each cycle and recorded for the duration of the experiment; compared with 4/4 ACUVUE^ OASYS MAX 1-DAY, 1-DAY ACUVUE^ MOIST, clarity^ 1day and MyDay^ contact lenses; p<0.01.
