With PureVision Toric lenses, Bausch + Lomb pioneered the way for reducing spherical aberration in the spherical power meridian. Now with PureVision2 HD for Astigmatism with high-definition optics, Bausch + Lomb scientists have optimized the optical design to reduce the spherical aberration across both, the spherical and cylindrical power meridians giving the astigmatic patient consistently crisp and clear vision.

Bausch + Lomb PureVision 2 contact lenses with high-definition optics and PureVision 2 for Astigmatism are designed to reduce spherical aberration across a broad range of powers.
