That's why these sport frames have patented vents on the side to make sure that, when things heat up, your lenses stay crystal-clear. And even when the wind's blowing, their integral hinges will keep them steady and in place.

Costa 580 Lens
Yellow light is the enemy on the water and on land. It's hard for the eye to process, and changes how you see the world. Costa 580 Lenses cut down on yellow light, allowing the eye to see more red, blue, and green. The result is purer vision with unmatched contrast, definition, and colors. 580P Lenses are made of lightweight plastic and provide excellent impact and scratch-resistance. 580G Lenses are made from scratch-resistant glass and offer the greatest clarity.
Copper Lens enhances contrast and reduces glare. Ideal for sight fishing, driving, and everyday wear.
