The 580 lens is a signature technology from Costa. It eliminates the harsh blue and dulling yellow hues, while enhancing the good blue, red, and green colors, resulting in a view comparable to high definition. In effect, these glasses lighten and brighten the world while simultaneously shading your eyes from the sun. And like all Costas, they are 99.9% polarized and block harmful UV rays. When it comes to cutting glare off the water, the world below the surface is suddenly more visible and the fish come out of their camouflage.
I tend to buy cheaper sunglasses because I am known to break or lose them, but I think my eyes have been suffering for it. Luckily, the polycarbonate lenses are super lightweight, very durable and scratch resistant. The mirrored finish on Costas is sandwiched between other layers, so will not peel off. So far my Copra’s have withstood SUPing on the Colorado River, hiking in sandy Moab and fishing the Roaring Fork and the lenses remain in mint condition, or as I like to call them “Jordan-proof.”
The frames are made from bio-resin, a reclaimed castor oil material that is petroleum free, part of Costa’s mission to Kick Plastic. The hinge is set back on the arm, making the frame more durable and less prone to snapping under pressure.
Hydrolite rubber pads on the nose keeps the frames comfortably and securely on your face, even when wet or sweaty. There is nothing worse than looking down to untangle a line or tie a shoelace and your glasses slide slowly toward the end of your nose. The stability, or stay-ability, of the glasses is further reinforced by textured grips on the end of the arms, to keep them snugly behind your ears.
And lets not forget style. The 580 lens comes in a variety of shapes and styles, but the Copra’s have a fashionable retro look that’s just as perfect for sports as for lounging poolside or walking the beach. There are several color combos, but my favorite is the classic tortoise shell.
