Alcon’s Dailies Total 1 is the first and only daily disposable lenses with nearly 100% water at the surface, so nothing touches the eye but a gentle cushion of moisture. This is known as Water Gradient Technology. The high breathability of Total contact lenses means more oxygen can flow through the lens to the eye, helping to keep eyes white and healthy-looking. Exclusive to Dailies Total 1 contact lenses, SmarTears Technology features the release of an ingredient found naturally in tears that helps to stabilize the lipid layer of the tear film. Nearly 9 out of 10 wearers agreed that Dailies Total 1 contact lenses are so comfortable they sometimes forget they are wearing them.
