Coopervision Serenity Toric (Previously called: Coopervision Sapphire) is a monthly disoposable lens for those with an astigmatism. Coopervision Serenity's unique silicone monomers mean that oxygen is transmitted very efficiently through the lens. This results in a lens with a very high oxygen transmission and high water content , for softer more comfortable lenses. There are 6 lenses per box.
