Sunglass frames are often made of Metal, Nylon, Plastic or Titanium.

• Metal Frame Sunglasses: Sunglasses with a metal frame are strong but rigid. They can bend permanently or even break when twisted.

• Nylon Frame Sunglasses: Nylon frames, often used in sport sunglasses, are lightweight, strong, and flexible.

• Plastic Frame Sunglasses: Inexpensive plastic frames are lightweight, strong, and flexible. A rubber coating on the bridge and earpieces of sunglass frames allow sunglasses to remain positioned on your face.

•Titanium Frame Sunglasses: Sunglasses with Titanium frames give you the best of both worlds when it comes to comfort and style. Sleek like a metal frame and durable like a plastic, titanium frames can be found at AmericanSunglass.com
