What Types of Lens Materials Meet ASTM F803 Standard?

ASTM F803 does not specify specific lens materials that meet the standard. However, certain lens materials are commonly used in sports eyewear that is designed to meet the ASTM F803 requirements for impact resistance and optical quality. Here are some lens materials commonly found in sports eyewear that are known for their impact resistance:

1. Polycarbonate: Polycarbonate lenses are widely used in sports eyewear due to their excellent impact resistance. They are lightweight, durable, and highly resistant to shattering.
2. Trivex: Trivex lenses are another popular choice for sports eyewear. They offer similar impact resistance to polycarbonate lenses but provide better optical clarity and are slightly lighter in weight.

It's important to note that while these lens materials are commonly used in sports eyewear and known for their impact resistance, the specific lens materials above are tested and labeled as meeting ASTM F803.
