Air Optix Aqua or Avaira? We recently received an email from Jennie in Uticah: "I have been using Avaira for almost 8 months. The lenses are fine but I noticed there might be other cheaper alternatives. I don't mind switching to a monthly lens like the Air optix lenses from Ciba or the biofinity lenses. Any recommendations?". As always, we can't make any recommendations, so we told Jennie to discuss her concerns with her eye care professional, however this comparison sheet provides some additional insight into the parameters and features of these two lenses.
