Acuvue Oasys for Astigmatism 6 Pack Fortnightly contact lenses offer exceptional comfort and provide stable vision. The Eyelid stabilised® design helps minimise lens movement and helps keep vision crisp, clear and stable all day long to help those with astigmatism - even those with an active lifestyle. Acuvue Oasys for Astigmatism protect eyes from potentially harmful UV rays and block out at least 96% of the UVA and more than 99% of UVB rays.UV absorbing contact lenses are not substitutes for protective UV absorbing eyewear such as sunglasses because they do not completely cover the eye and surrounding area - you should continue to use UV absorbing eyewear as directed.
