LiteForce - Forged at extreme temperatures, LiteForce is a patented thermoplastic material that''s flexible, lightweight and durable. Thermoplastic is used in various high-tech industries including aerospace, automotive and medical technology. Lens Tech
100% UVA/UVB Protection - These lenses provide complete protection from the harsh rays of the sun.
Impact Resistant - Ray-Ban lenses are 2x more resistant to impacts than the industry standard. All Ray-Ban lenses are tested to withstand the impact of a steel ball dropped from 1.27 meters.
Scratch Resistant - Ray-Ban lenses are tested to withstand 500 grams of a special abrasive sand oscillating for 600 cycles. Compared to the most commonly prescribed lenses (CR-39), Ray-Ban lenses are 12 times more resistant to scratching than the industry standard.
Element Proof - All Ray-Ban lenses must undergo 120 hours of exposure to UV light, moisture, heat, organic solvents, sea salt and sweat acidity, without exhibiting any visible change in the color or surface of the lens. Frame Measurements (mm)
These measurements include the diameter of the lens, the width of the bridge and the length of the arms measured in millimeters. For example, a 59-15-135 frame breaks down like this:
Lens Diameter: 59mm
Bridge Width: 15mm
Arm Length: 135mm 52-20-150
