I learned a trick when I was an AG swimmer as a teenager that I still use today: splash some water on your face to wash off any oil around your eyes before you put on your goggles, that way you get a tighter seal.

I pretty much never get leaky goggles, and I've used all different brands/styles over the past 20+ years.

I also usually readjust my goggles between sets, but that's probably just a habit from when I was a fidgety kid.
