PureVision Toric - recommended for correction of astigmatism - is a monthly disposable contact lens with an enhanced optical design that creates crisp, sharp vision beyond what you are likely used to – especially at night and in low light conditions.
PureVision Toric is also the first family of silicone hydrogel lenses made of AerGel™, a unique material designed to deliver extraordinary comfort and health.
In addition to providing exceptional comfort and health benefits, the PureVision Toric soft contact lens is designed to reduce spherical aberration, that affects visual quality in low-light conditions (objects appear blurred or hazy). Spherical aberration is a natural occurence, in which light rays are refracted at different angles as they enter your eyes. It remains, even after basic vision conditions like near-sightedness have been corrected.
Researchers estimate that nearly 70-percent of the population has spherical aberrations.
They may be worn for up to 30 nights (one month) of continuous wear based on how your eyes respond to lens wear and your eye care professional’s recommendation.
