TOTAL30® contact lenses use a revolutionary Water Gradient Technology that creates a gradual transition in water content from 55% at the core to nearly 100% water at the outermost surface—so the eye only touches a cushion of moisture. CELLIGENT® Technology mimics the cornea, repelling bacteria and lipids for a clean lens all month. In addition, they block more than 90% of UVA rays and 99% of UVB rays.
