Bausch & Lomb’s PureVision contact lenses marked a major step forward in contact lens design. Made from balafilcon A silicone hydrogel, these monthly lenses allow more oxygen to reach the cornea, reducing redness and dryness throughout the day.
With 36% water content and FDA approval for up to 30 nights of continuous wear, PureVision remains a dependable choice for those seeking comfort, clarity, and long-term eye health.
What Makes PureVision Lenses Different
PureVision lenses balance oxygen permeability and moisture retention—two essentials for maintaining healthy eyes. Traditional hydrogel lenses often limited oxygen flow, leading to discomfort after long hours of wear.
PureVision’s silicone hydrogel structure ensures that the eyes stay hydrated and clear, even with extended use.
- Diameter: 14.0 mm
- Base curves: 8.3 mm and 8.6 mm
- Power range: +6.00 D to –12.00 D
These fitting parameters make the lenses adaptable for various prescriptions and eye shapes.
Comfort, Clarity, and Oxygen Flow
PureVision lenses maintain a moderate water level while maximizing oxygen transmission. This balance reduces the risk of corneal swelling and irritation. Many wearers notice whiter, more relaxed eyes after switching from standard hydrogel lenses.
- Aspheric optics minimize spherical aberrations, producing clearer, high-contrast vision even in dim lighting.
- AerGel® surface treatment modifies silicone’s naturally dry texture into a wettable surface, allowing tears to spread evenly for consistent comfort.
These innovations make PureVision particularly suitable for people who spend long hours on screens or frequently drive at night.
Extended Wear and Safety Considerations
PureVision lenses are approved for up to 30 nights of continuous wear. However, not everyone qualifies for overnight use. Ideal candidates are those with:
- Healthy tear film and corneal sensitivity
- No history of eye infections or severe dryness
Eye care professionals typically recommend a gradual adjustment period with regular follow-ups to ensure corneal health. Even with excellent oxygen flow, extended wear carries higher risks of irritation or infection. Lenses should be removed immediately if redness, pain, or vision changes occur, and replaced monthly as directed.
Care and Maintenance Guidelines
Proper hygiene is critical for performance and safety:
- Wash and dry hands thoroughly before handling lenses.
- Use a multipurpose or hydrogen-peroxide solution formulated for silicone hydrogel lenses.
- Replace solution daily—never top off old liquid.
- Clean lenses by gently rubbing and rinsing after each use.
- Avoid water exposure while swimming or showering.
For added longevity, weekly enzymatic cleaning removes protein buildup, while replacing the lens case monthly minimizes contamination risk.
User Impressions and Performance
User feedback highlights PureVision’s strong optical performance:
- Sharper vision and reduced glare are common benefits.
- Improved comfort during long workdays, especially in air-conditioned spaces.
- Extended-wear users value the convenience of overnight use, though comfort levels vary.
Mild to moderate myopes report the highest satisfaction, while those with astigmatism or presbyopia often prefer specialized versions such as PureVision Toric or PureVision Multifocal.
Comparing PureVision with Other Lenses
Within Bausch & Lomb’s lineup, PureVision serves as the foundation for its modern silicone hydrogel technology. The updated PureVision 2 refines the design with a thinner edge for greater comfort.
When compared to competitors like ACUVUE Oasys or Air Optix, PureVision offers similar oxygen permeability and optical clarity, though differences in surface coating create slight variations in feel.
From a cost perspective, PureVision provides substantial savings over daily disposables—often 50–70 percent annually—making it ideal for users seeking advanced material benefits without daily replacement costs.
Why PureVision Remains a Trusted Choice
PureVision contact lenses deliver a well-rounded combination of comfort, vision quality, and eye health benefits:
- High oxygen transmission keeps corneas healthy and reduces redness.
- Aspheric optics ensure crisp vision in daylight and low-light conditions.
- Monthly replacement offers a practical balance between cost and convenience.
- Extended-wear approval gives flexibility for those with active schedules.
While users with severe dryness or sensitivity may prefer other materials, PureVision continues to stand out as one of the most balanced options in monthly silicone hydrogel lenses.
For wearers seeking dependable clarity and sustained comfort, it remains a proven solution recommended by eye care professionals worldwide.
