Wear Costa Ocean Ridge 210 eyeglasses when you want durable, sporty frames that enhance your lifestyle. The bio-based, TR-90 nylon resin frames use trifusion bonding technology to produce durability under harsh conditions. The lightweight-frame eyeglasses for men or women are resistant to heat, cold, and corrosion. They feature skull temples and textured nose pads to provide a firm grip and minimize slippage. The saddle bridge and slight flair at the end pieces create an attractive profile, and the rectangular shape accentuates round, oval, and heart-shaped faces.
