PureVision Toric continuous silicone-hydrogel contact lenses correct astigmatism and promote high quality vision. They’re one of the most popular toric lenses on the market and should be replaced monthly. The PureVision Toric contact lenses are no longer in production. The only versions available are the ones currently in stock. Users of the PureVision Toric contacts can start using the new PureVision 2 for Astigmatism lenses without a new prescription. Due to their different parameters, we recommend consulting the new prescription with an ophthalmologist.
