The Rudy Project hi+ 1.6™ provides far superior optics and scratch resistance when compared to traditional polycarbonate lenses and will offer amazing impact resi- stance over traditional plastic or glass lenses. They have superior optical qualities, eli- minate distortion, greatly enhanced cosmetic appearance, and offer lighter weight for unsurpassed comfort.

High index lenses have a lower specific gravity than their traditional glass and plastic counterparts. Translated, these lenses are less dense. Other aspects, such as center thickness, decentration, and frame choice will also impact the finished product. The advantage of this is that a lens can be created using less material, therefore having less bulk and weight. Minus lenses are thicker at the outer edge; a high index lens decreases this, diminishing the bottle effect when seen form the side. Internal reflections will also be decreased.

Lenses with higher indices also reflect more than standard plastic and glass. Because of this, anti-reflective coating is especially important. Additional reflections will be distracting in day to day activities such as night driving and computer use. Impurities, water drops, dust, scratches will heavily influence the comfort of high index lenses, for these reasons, Rudy Project offers 2 optional coatings:


  • AR coating, our quality standard anti-reflection coating
  • Diamond Coat™, our new premium coating.
