LENS QUALITY

Lens material
Three different lens materials are primarily used to manufacture Filtral glasses:
Acrylic glass (AC)
- Made from Polymethyl methacrylate (PMMA)
- Stronger than mineral glass – higher breaking resistance and low risk of shattering
Polycarbonate lenses (PC)
- Primarily used for sports glasses or children's glasses
- Extremely high breaking resistance and highly shatter resistant
- Sunglasses: Always equipped with particularly effective protection against UV rays
Polarised lenses for sunglasses
- Polarisation filters reduce disruptive glare, e.g. from wet or shimmering roads, in snow, from light sand or from water surfaces
- Ensure glare-free and high-contrast vision
- Improve spatial perception
- Reduce eye strain
