PureVision 2 HD toric are extended-use silicon hydrogel toric contact lenses to be worn for one month. The design ensures outstanding comfort, and high-quality optics reduce spherical aberrations to ensure clear vision. The special surface maintains moisture and reduces the formation of sediments on the contact lenses. The special prism support and large diameter of these contact lenses ensure immediate stability, precise centring during various eye movements and glances aside, as well as comfortable vision all day long. The thin and rounded edges of the contact lenses improve the circulation of tears so as to protect, nourish, moisten and clean the cornea.
