My last pair of glasses (first with PALs) had Varilux Comfort lenses and my new pair have Essilor Ovation lenses -- now I understand what people are talking about when they discuss "swim".

It's been two days and I'll give it a couple more to see if I adjust to it, but I don't remember this at all when I first received the Comfort lenses.

Before I return to discuss this with my ECP, I'm curious if this swim effect is due more to the design/construction of the lens itself or a possible fitting issue.
