Costa-Sunglasses: Beyond Polarized
Costa Sunglasses: Beyond Polarized Where Glare Goes To Die. Most polarized lenses eliminate glare by blocking reflected light. But Costa's patented 580 lenses go farther, blocking perfect amounts of harsh yellow light while enhancing reds, blues and greens.
The result: less haze, less blur, greater contrast and greater clarity. Available in glass (580G), or a lightweight, impact-resistant plastic (580P), it's like seeing in high definition.
