The other solution is to go fully cheap and buy the $7 Smith and Wessons (& others) with the traditional sunglass-like shape. And, you can buy 'em in any color you like seeing as they are nearly free. At least when you inevitably lose (or break) them, you won't be so torn up.
That is my ploy for shades for high performance boating. Although I wear "mirrored" aviator RayBans when driving on the roads, when I run a hi-perf boat I wear a pair of $10 shades that won't break me if they blow off at 90 mph. I blew a pair of RayBans into the river last year. Not again.
