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

Polarized 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

Reading glasses with Blue Light Filter

• Integrated Blue Light Filter protects the eyes when using a computer, smartphone or tablet
• Approx. 30% of the artificial blue light is absorbed
• Reduce eye strain and fatigue
• Increased comfort and reduced glare at the same time
• Improved perception of contrasts and details
• 100% UV protection
