the goggle factor

Hi everyone: I'm a newby to masters, having had a 30-year break from competitive swimming back in my younger days. Back in the day, I never wore goggles during competition, & now that I have a meet coming up (feeling the butterflies already!), I am wondering if there are any tricks in the trade as far as keeping your googles in place during the start. I notice straps both under & on top of the cap. Is the strap tightened so that it feels like your eyes will pop out? I'm also interested in what brand/type of goggle is your favorite... thanks!
