LENS QUALITY
Two different lens materials are essentially used in the manufacture of our Filtral glasses. Made with OC-LIGHT LENS technology, the plastic lenses are also noticeably lighter and thinner.
ACRYLIC GLASS (AC)
- Used for sunglasses and reading glasses
- Made of the acrylic material polymethylmethacrylate (PMMA)
- Stronger than mineral glass – higher fracture resistance and low risk of shattering
POLYCARBONATE LENSES (PC)
- Used for sunglasses
- Used mainly for sports eyewear or children’s glasses
- Extremely high resistance to breakage and shattering
- Sunglasses: always provide particularly effective protection against UV-rays
In addition to different lens materials, certain filters are used in selected eyewear models.
POLARIZATION FILTER
- Finishing for sunglasses
- Polarization 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
BLUE LIGHT FILTER
- Finishing for reading glasses
- 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
