Product Description PureVision2 for Astigmatism are toric contact lenses by Bausch & Lomb, designed to reduce spherical aberration across the meridians of the lens for incredible vision. These lenses will provide a comfortable wearing experience for up to 16 hours a day and can be worn for up to 30 days. An Auto Align Design helps these lenses to remain stable on your eyes throughout the day, minimising rotation when your head or eyes are moving. As a result, they deliver sharp, balanced vision unaffected by visual distortions, blurs or halos. PureVision2 for Astigmatism are silicone hydrogel contact lenses which allow up to six times the amount of oxygen through to the eyes than a standard hydrogel lens. This promotes health and comfort, with oxygen keeping your eyes feeling fresh all day long, while water retaining qualities and moisture rich packaging offer long lasting hydration. As monthly lenses, they must be removed before you go to sleep and cleaned and stored in contact lens solution. Need more optical advice help? Ask our optical experts
