Acuvue Vita for Astigmatism are made from a non-coated silicone hydrogel material that provides exceptional comfort and breathability by retaining moisture within the lens throughout the month. Enhanced oxygen transmission across the lens is partly enabled by the innovative Hydramax™ Technology incorporated into the lens, supporting dependable all-day wear. The Blink Stabilized® design works with your eye’s natural shape and blinking motion to keep the lens properly positioned, helping ensure optimal vision and clarity. In addition, these lenses provide the highest level of UVA/UVB protection available in a monthly contact lens, helping protect your eyes whether indoors or outdoors.
