These goggles are likely going to keep your eyes mostly dry and you'll be able to see okay out of them. However if they're anything like my pair, they will get weirdly streaky on the inside, and fog up a bit. Not much! Juuuust enough where you can't see, for example, who your coach is talking to in which lane, even though you're wearing your contact lenses.And if your pair is anything like mine, then you'll have one HECK of a time switching out the nose pieces. The one that came by default was for a larger face with wider set eyes which, I have a fairly large face and wide set eyes but the goggles would suction down towards the outer edges of my eyes which felt uncomfy. I decided to swap out nose pieces. I hurt my fingers doing so. I'm here to whine about it so you can be mentally fortified for this task in a way that I was not. Godspeed. May your goggles be fog-free and your coach's face be crystal clear to you. :)
