Contact Lenses & Care

New and improved PureVision® Contact Lenses, with a smoother anterior surface delivers enhanced comfort for your patients while offering the same exceptional superior visual performance.  Also, 28% lower modulus. The same aspheric anterior surface that successfully reduces spherical aberration.

PureVision contact lenses for 30 days/29 nights of continuous wear are a significant breakthrough in contact lens technology. The innovative AerGel^TM technology provides a unique combination of silicone for high oxygen permeability and hydrogel for excellent fluid transport. The unique Performa^TM surface process transforms hydrophobic silicone into a smooth, consistently wettable, hydrophilic silicate surface. PureVision contact lenses offer a new level of performance.
