The 5 pound ‘swedish’ ones with the tiny hard bits for each eye will still suck your eyes. The fancier ones like those speedo ones don’t.
I don’t need goggles to swim outdoors in fresh water, or to swim breaststroke, but in a pool, i find a massive difference when swimming crawl – you just are so much more aware of everything going on around you.
Also, when learning crawl, most people suggest breathing every third stroke, so you don’t get unbalanced. And don’t lift your head to breathe, just roll it. Swimsmooth web site (google it) has lots of good tips for learning crawl (they sell books and things, but at least to start off with the website has lots of free info).
