PureVision Contact Lenses

Why PureVision Lenses Perform So Well

• AerGel™ Material Technology: The foundation of the entire PureVision range. This advanced silicone hydrogel material is uniquely formulated from Balafilcon A — a material with exceptional oxygen transmissibility that allows natural oxygen to flow continuously through the lens to the cornea, even during overnight wear.
• ComfortMoist Technology: Wraps PureVision lenses in a moisture-rich surface treatment that prevents end-of-day dryness and maintains a consistent, comfortable wearing experience from insertion to removal.
• High Definition (HD) Optics: Built into PureVision 2, this technology reduces spherical aberration — the optical imperfection responsible for halos and glare around bright lights — delivering crisper, clearer vision in low-light conditions and while driving at night.
• Protein Deposit Resistance: The Balafilcon A silicone hydrogel used in PureVision lenses is inherently resistant to protein and lipid deposits, helping maintain lens clarity and in-eye comfort throughout the full 30-day replacement cycle.
• Auto Align Design: Used in PureVision 2 for Astigmatism and PureVision Toric, this toric stability system works with your natural blink reflex to continuously realign the lens on the correct astigmatism axis, ensuring consistent, blur-free vision.

Which Purevision Lens Is Right For You?

Here's a practical guide to the lenses we stock online, plus a clear path for wearers who need something more specialised. Your optometrist will always confirm the right fit — but this should help you arrive at that conversation knowing what to ask about:

• You want the premium, modern monthly lens with sharper night vision: PureVision 2 HD is available as a standard stocked lens with normal delivery timeframes. It's thinner than the original PureVision and adds High Definition Optics to specifically reduce halos and glare in low light — the upgrade worth discussing if night driving or screen glare has been a concern.
• You have astigmatism and need stable, sharp monthly correction: PureVision 2 for Astigmatism is available as a standard stocked lens. It combines HD Optics with the Auto Align toric stabilisation system — delivering both optical clarity and consistent lens positioning through an active day. If you were previously wearing the original PureVision for Astigmatism, this is the most appropriate transition lens to discuss with your optometrist.
• You are a current PureVision original wearer and want to continue while it remains available: The original PureVision remains available made to order — please allow 3–8 weeks for delivery. If you have been approved for extended or overnight wear, this remains the appropriate lens to continue ordering while available. Plan your orders well in advance given the lead time.
• You have presbyopia and need clear vision at near, intermediate, and distance in a monthly lens: You have two options within the PureVision range. PureVision 2 HD for Presbyopia is the more advanced choice — it combines the thinner lens design and HD Optics of PureVision 2 with a multifocal optical design, and is available as a standard stocked lens with normal delivery timeframes. The original PureVision Multifocal also remains available for wearers already established on this lens, but is made to order — please allow 3–8 weeks and order well ahead of when your current supply runs out. Your optometrist can advise which suits your specific prescription and vision demands.

Frequently Asked Questions

Can I sleep in PureVision contact lenses?
Yes, PureVision and PureVision 2 lenses are FDA-approved for extended wear for up to 30 continuous nights. However, you must only sleep in your lenses if your optometrist has specifically evaluated your eyes and prescribed this modality. Even with approved extended wear lenses, sleeping in contacts increases the risk of eye infections by 6 to 8 times compared to daily wear. Always follow your optometrist's guidance.

What is the difference between PureVision and PureVision 2 HD?
PureVision 2 is the modern upgrade to the original PureVision lens. Both are made from Balafilcon A silicone hydrogel and are FDA-approved for extended wear. However, PureVision 2 features a thinner, more refined lens design and the addition of High Definition Optics, which are specifically engineered to reduce the halos and glare often caused by digital screens and low-light environments.

Is PureVision good for people with dry eyes?
PureVision lenses are designed with ComfortMoist surface technology and a naturally deposit-resistant material, which helps maintain comfortable wear throughout the day. However, wearers with severe dry eye conditions should consult their optometrist before choosing any monthly lens, as daily disposables may be a more suitable option for highly sensitive or dry eyes.

What prescriptions are available in PureVision lenses?
The PureVision range covers a wide spectrum of prescriptions for short-sightedness (myopia), long-sightedness (hyperopia), astigmatism (PureVision 2 for Astigmatism), and presbyopia (PureVision Multifocal). Because many PureVision prescriptions are made to order, some parameters may have a longer lead time than off-the-shelf lenses. Your optometrist can advise on availability for your specific prescription.

Are PureVision contact lenses made to order?
Yes. The original PureVision range is a legacy brand from Bausch & Lomb, which means the manufacturer now produces these lenses on a made-to-order basis rather than holding them in standard stock. Delivery can take up to 3 to 8 weeks to arrive from the manufacturer. If you currently wear an original PureVision lens, it is important to place your order well before your supply runs out, or consult your optometrist about transitioning to a more readily available modern alternative, such as PureVision 2.
