Purevision contact lenses by Bausch + Lomb are designed to provide exceptional breathability and long-lasting clarity for those seeking a reliable monthly replacement schedule. Utilizing an advanced silicone hydrogel material, these lenses are engineered to support ocular health by allowing a significant flow of oxygen to the eye, helping to keep them white and healthy-looking even during long periods of wear.
Please Note: Purevision is a legacy brand and is now made to order by Bausch + Lomb. Due to this specialised manufacturing process, please allow 3 to 8 weeks for your lenses to be produced and dispatched.
The Clinical Advantages of AerGel Technology
- AerGel™ Matrix: This proprietary material composition balances oxygen and moisture, ensuring the cornea receives a continuous supply of oxygen while maintaining a stable tear film to support hydration.
- High Oxygen Transmission: The silicone hydrogel material, Balafilcon A, is significantly more breathable than traditional hydrogel options, making these extended wear contact lenses suitable for flexible wearing cycles.
- Performa™ Surface Treatment: This specialized manufacturing process creates a smooth, hydrophilic surface that actively resists the buildup of proteins and lipids, ensuring the lenses stay clear and comfortable for the full 30-day duration.
- Sharp Vision with High Definition Optics: The advanced aspheric design is specifically crafted to minimize spherical aberration, providing patients with crisp vision and reducing visual disturbances like halos or glare in low-light environments.
Who Should Consider Wearing Purevision?
Optometrists frequently recommend Purevision for patients who:
- Require optical correction for myopia (short-sightedness) or hyperopia (long-sightedness).
- Are looking for monthly contact lenses that offer the flexibility of an extended wear schedule.
- Experience symptoms of ocular redness with standard lenses and need the high oxygen flow of silicone hydrogel lenses.
- Have been specifically fitted for this legacy product and are comfortable with a 3 to 8-week manufacturing lead time.
Note: Suitability, fit, and replacement schedules must always be confirmed by your optometrist.

Common Questions About Purevision
Can I sleep in Purevision contact lenses?
Purevision lenses are FDA-approved for up to 30 days of continuous wear, which includes sleeping in them. However, it is critical that you only follow an overnight wear schedule if your regular optometrist has evaluated your eye health and explicitly approved an extended wear pattern.
What is the difference between Purevision and Purevision 2 HD?
Purevision 2 HD is the modern, upgraded successor to the original Purevision. It features a thinner lens profile for enhanced initial comfort and incorporates ComfortMoist technology in the packaging solution. While Purevision is a made-to-order legacy lens with a multi-week lead time, Purevision 2 HD is a standard stock item available for rapid dispatch.
Why is there a manufacturing delay when I buy Purevision online?
Because Purevision is a legacy brand, Bausch + Lomb no longer maintains a ready-to-ship inventory of these lenses. Each order is custom-manufactured to match your specific prescription. If you require lenses urgently, consult your eye care professional about upgrading to the more recent Purevision 2 HD.
