Plastic sunglasses

What are the types of frame material?

In general, eyeglasses are made of metal or plastic, or a combination of both. What suits you best varies depending on your personal preference, lifestyle, and situation.

Plastic frame materials

1. Zyl or cellulose acetate. Inexpensive and lightweight, zylonite or Zyl is one of the easiest frames to adjust.

Metal frame materials

2. Beryllium. People who often work in and around saltwater can choose beryllium. It is strong and flexible, making it easy to adjust.

3. Monel. This material is a combination of several metals and is coated to prevent allergic reactions from its components like nickel.

4. Stainless steel. Although light and strong, stainless-steel frames tend to be heavier compared to titanium.

5. Aluminum. High-end frames use aluminum because it boasts top-grade flexibility, strength, and corrosion resistance.

6. Flexon. This metal is a titanium alloy and comes back to its original shape even after twisting or bending.
