A comparison of ACUVUE OASYS and Avaira Vitality. What are the differences? This detailed up-to-date comparison shows the similarities and differences in material, parameters, special features, and daily cost.
Both lenses are bi-weekly replaceable silicone-hydrogel lenses with Class 1 UV blocking. While Vitality is indicated for daily wear, ACUVUE OASYS® can be worn up to 6 nights based on your eye care professional's recommendation. In addition and based on a higher Dk/t value, ACUVUE OASYS® allows more oxygen to get through the lens to the eye.
