Extended contact lenses – is there a difference between Ciba Vision Air Optix and PureVision B & L?
The Air Optix are twice as expensive and I wonder if they are better or a little more expensive than Purevision?

out of these two lenses the best would be air optix. they are both ok lenses but most people find that the purevision lenses tend to feel dryer in thier eyes than air optix. the best lens for extended wear is Acuvue Oasys. Its much thinner and far more moist than the two you have mentioned. Whenever I fit my patients with extended wear lenses I give them a trial of all these lenses and nearly all my patients have chosen the Oasys lens for its superior comfort. Oasys is replaced more frequently so its also healthier for your eyes.
