Smith Optics' Capital sunglasses certainly fit these criteria. Best known for making first-rate goggles for skiing, snowboarding, and motorsports, Smith also crafts a killer pair of shades. The Capitals boast rugged, Grilamid TR90 frames and Techlite glass lenses. The pads at the nose and temples relieve pressure and keep the glasses securely in place. You can hang your head upside down and the Capitals won't slide off, which just might save your bacon the next time you go to clear the rudder, pick up the mooring, scrub the scum line, etc. The styling is brilliantly basic: sporty, but not techy; close-fitting, but not wraparound. This is everyday eyewear that won't let you down on the water.
