I am not in the study but I bought the Aqua Sphere Kayenne goggle (silver w/smoke lens) back in September after seeing Bruce Gennari in them at a race. It’s been my only goggles ever since; through three pool workouts per week, a few open water workouts, and one sprint race. The smoke lens works well in indoor pool lighting as well as open water and racing.
I do get comments about the Batman-like look but they are very comfortable (sits over the eye sockets) and they have worked well for me, so far. My only negative is the higher price but at nearly 9 months of regular use, it appears that I’m getting good durablility as well.
I’ve never noticed the vision issue Slowman mentioned. I do wear corrective glasses (nearsighted) so maybe I just didn’t notice.
Yes, I will buy another set.
