Acuvue Advance for Astigmatism vs. Oasys for Astigmatism |
|
For patients with astigmatism we have compared the 2 toric lenses Acuvue Advance for Astigmatism and Acuvue Oasys for Astigmatism. Latter one was just recently introduced (June 2008), so we had a closer look at both lenses to show you the differences.

As most Acuvue products these 2 toric lenses come with first class UV blocking and convenience features such as inside-out-mark and visibility tint. However, the younger Acuvue Oasys for Astigmatism provides some significant improvements over Acuvue Advance for Astigmatism. The much higher oxygen permeability of Acuvue Oasys for Astigmatism should provide patients with improved wearing comfort. In addition it shows a more flexible replacement schedule as patients can wear the lens up to 6 consecutive days and nights. Acuvue Advance for Astigmatism comes with a lower price tag - typical online retail prices indicate that Acuvue Advance for Astigmatism is up to 15% cheaper than the toric Oasys.
