Luxottica shapes aerospace alloys into virtually indestructible frame components and transforms purified polymers into optically precise lenses. Rare-earth oxides are infused for enhanced visual contrast, nano particles are diffused into abrasion-resistant coatings, and molecules are engineered to filter polarized light. Few customers will ever comprehend the level of technology involved, but the best eyewear on earth demands nothing less. That is why Luxottica holds more than 600 patents worldwide.
