PureVision vs PureVision 2

Updated: Feb 6, 2020

With Purevision 2 and PureVision we are looking at two monthly replaceable contact lenses from Bausch & Lomb. What are the differences?

Comparison Highlights

• Purevision was introduced in 2005 and Purevision 2 followed in 2011.
• The base material of these two lenses is Balafilcon A, a silicone hydrogel with a water content of 36%.
• The lenses are similar, except for the base curve parameter and the ability to transfer oxygen. Purevision is offered with a base curve of 8.3mm or 8.6mm which means that your eye care practitioner has another option available in the fitting process.
• The ability to let oxygen pass through the lens to your eye is 20 ticks higher in the Purevision 2 lens (130Dk/t). This is a significant upgrade from the original PureVision.
• As the daily cost per eye is also the same, there isn't any reason to not consider the newer PureVision 2.
