ACUVUE OASYS for ASTIGMATISM features a unique BLINK STABILIZED lens design that actively prevents toric lenses from rotating in the eye. Similar to standard ACUVUE OASYS, these lenses utilize HYDRACLEAR®PLUS technology which allows for a unique, oxygen rich environment for long-term comfort. These lenses also block a high level of UVA and UVB rays to help protect portions of your eyes.
