PureVision 2 HD for Astigmatism contact lenses are engineered to provide consistently sharp, clear vision for those who require precise correction for astigmatism. These Bausch and Lomb toric lenses focus on delivering high-definition optics and exceptional rotational stability, ensuring that vision remains crisp even during active movement or in challenging lighting conditions.
High-Definition Optics for Enhanced Visual Clarity
The primary innovation behind these contact lenses for astigmatism is High Definition™ Aspheric Optics. This advanced design is specifically intended to reduce spherical aberration—a common cause of blurred vision and halos. By focusing light to a precise point on the retina, the lenses help wearers experience vibrant contrast and reduced glare, which is particularly beneficial for tasks like night driving or working in dimly lit environments.
Advanced Stability and Moisture Technology
To ensure the corrective power stays exactly where it is needed, PureVision 2 HD for Astigmatism utilizes the Auto Align Design™. This hybrid ballasting system uses the natural pressure of the eyelids to keep the lens stable on the eye, preventing the blurred vision often caused by lens rotation. Furthermore, the integration of ComfortMoist™ technology—a combination of a thin lens profile and a moisture-rich storage solution—promotes immediate comfort from the moment of insertion and helps the lens glide smoothly over the ocular surface throughout the day.
Who Should Wear PureVision 2 HD for Astigmatism?
These monthly silicone hydrogel lenses are a reliable choice for daily wearers who need to correct myopia or hyperopia alongside their astigmatism. Optometrists frequently recommend this profile for patients who:
- Have a diagnosed astigmatic prescription that requires stable toric correction.
- Frequently experience visual disturbances, such as starbursts or halos, around artificial lights at night.
- Lead an active lifestyle where lens movement and rotational stability are critical for maintaining clear sight.
Note: Suitability, fit, and replacement schedules must always be confirmed by your optometrist.

Common Questions About PureVision 2 HD for Astigmatism
Can I wear PureVision 2 HD for Astigmatism lenses overnight?
PureVision 2 HD for Astigmatism is manufactured using Balafilcon A, a silicone hydrogel material that allows high levels of oxygen to reach the eye. While they are designed for monthly daily wear, they are also clinically approved for up to 30 days of continuous wear. However, any extended or overnight wear schedule must be specifically assessed and approved by an optometrist to ensure it is safe for your individual eye health.
Why is PureVision 2 HD for Astigmatism better for night driving?
Standard lenses can sometimes struggle with spherical aberration, which causes light to scatter and create halos around streetlights or headlights. PureVision 2 HD for Astigmatism features aspheric optics that specifically address this issue, sharpening the focus and improving contrast. Combined with the Auto Align Design™ that keeps the toric correction stable, wearers often report much clearer and more confident vision behind the wheel at night.
How should I care for my PureVision 2 HD for Astigmatism lenses?
As a monthly replacement lens, PureVision 2 HD for Astigmatism requires a nightly cleaning and storage routine if not worn continuously. Using a high-quality multi-purpose solution, such as Optifree Pure Moist, will help remove protein deposits and debris accumulated during the day. Always store the lenses in a clean contact lens case with fresh solution to maintain hygiene and comfort.
