LENS QUALITY

header lens quality, device for processing eyeglass lenses

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
