Frame Materials
Plastics
Zylonite (zyl): An inexpensive and lightweight plastic used in a wide variety of brightly colored frames.
Optyl: Optyl is hypoallergenic, making it a great choice for kids and adults with sensitive skin.
Nylon: A flexible plastic that withstands extreme temperatures. Blended nylon frames are lightweight and strong.
Kevlar®: Impact-resistant Kevlar® keeps its shape for years. It is most commonly used to fortify sports and performance sunglasses.
Metals
Stainless Steel: Stainless steel frames are slim, strong and easily adjustable. They resist moisture and rust, but are less flexible than monel and memory metals.
Titanium: Featherweight titanium can be molded into a wide variety of shapes. It is anti-corrosive, hypoallergenic and one-third stronger than steel.
Cobalt: Often found in designer and specialty sunglass lines, cobalt frames are durable, flexible and thin.
Aluminum: Lightweight and resilient aluminum frames are sleek and stylish.
Monel: Monel is a popular choice among sunglass manufacturers because of its versatility. It can be extensively shaped without losing its strength.
Memory Metals: Highly durable memory metals retain its original shape for a long-lasting fit. Memory metals reinforce the frame's bridge and temples, making glasses virtually indestructible.
Composites
Carbon Fiber/Graphite: A blend of nylon and carbon that holds up in extreme conditions.
