All the sunglasses will fall off eventually. You just tie the tape from your wetsuit zip onto the headband as a safety leash.
Those Ladgecom ones look pretty tricky with the various modular bits and pieces and the price is quite good.
I have used Oakley Waterjackets (not particularly good, very expensive and now discontinued), and Sea Specs (
www.seaspecs.com ) and they all work ok. The Sea Specs were best because they were cheapest at three pairs for $100.
The ones shaped like glasses have the problem where water pools inside the frames and they fog up and it's hard to get a finger under to give your eye a wipe.
I am currently using Spex with the yellow lens.
spexusa.com/ They are the best I have tried by a long way. The yellow lens means I can wear them in bright sun and keep them on well into dusk and still be able to see. They keep the spray out of my eyes and the water and fog proof coatings seem to work ok. They are easy to slide up and down or to give my eyes a rub. The only problem is that they are big. The look and fit a bit Fearless Fly.
