PureVision 2 and Acuvue Oasys are popular silicone hydrogel contact lenses. Each provides exceptional comfort and visual acuity for wearers, but they also have distinct features, designs and replacement schedules.
PureVision 2 and Acuvue Oasys are available for daily wear and optional continuous wear. However, PureVision 2 are monthly lenses that can be worn continuously for up to 30 days before removal. Acuvue Oasys are bi-weekly lenses that can be worn continuously for up to seven days before removal.
The aspheric design of PureVision 2 results in sharp vision and allows for quick focussing when working on a computer or during fast-paced activities such as sports. Acuvue Oasys are spherical contact lenses with excellent imaging properties. The better option ultimately depends on your eyes, preferences and recommendations from your eye doctor.
