8. Next Previous Trivex material is a unique category of lens material made possible only through complex chemistry and advanced production methods. From the optical materials expertise of PPG Industries comes this high technology lens material that is perfect for the majority of eyeglass wearers. ADVANCED TECHNOLOGY HistoryUnique ProductionAdvanced Science

9. Next Previous Originally developed as helicopter windshields and fighter jet canopies for the military, this advanced polymer technology provided extreme impact resistance, optical purity and ultra-lightweight performance. In development for more than a decade by the U.S. military, the technology was subjected to rigorous ballistic and extreme performance testing. FROM THE BATTLEFIELD TO THE BACKYARD… HistoryUnique ProductionAdvanced Science

10. Next Previous PPG Industries recognized the value of this unique material and began adapting the chemistry for consumer eyewear. In collaboration with optical industry partners, PPG introduced Trivex material in 2002 as a revolutionary new category of lens material to eyeglass wearers around the world. As eye care professionals continue to embrace Trivex material, PPG continues to develop the material and work with their partners to expand the availability of lens designs and formats. Today, a wide range of patients can benefit from the unique benefits of Trivex material. FROM THE BATTLEFIELD TO THE BACKYARD… Unique ProductionAdvanced ScienceHistory

11. Next Previous HI-TECH CHEMISTRY FOR EVERYDAY LIFE HistoryUnique ProductionAdvanced Science Trivex material is built on polyurethane chemistry similar to many optical lens materials. PPG chemists found a way to enhance the base polyurethane molecule by enriching it with additional nitrogen. The result is a lens material that is not only optically superior but also exceptionally strong and ultra- lightweight.

12. Next Previous HI-TECH CHEMISTRY FOR EVERYDAY LIFE HistoryUnique Production As a natural result of the chemical reaction that occurs during the casting process, a reinforcing structure self-assembles at a nano-scale. This structure is comprised of hard and soft regions that gives the lenses high impact resistance and durability, but is too small to interact with light and interfere with the optical clarity of Trivex material. "Nano-domains" in Trivex material are approximately 30-50nm in diameter… while a human hair is approximately 10,000nm thick. Advanced Science

13. Next Previous 2 COMPONENTS HistoryUnique ProductionAdvanced Science Trivex material is a two component system. Each component must be handled carefully and cannot be exposed to air from the moment they are created to the moment they are mixed together. 1 2345

14. Next Previous MIXING HistoryAdvanced Science A specially designed machine mixes the components at a precise ratio and temperature. Any variation in these parameters results in a poor quality lens. The chemical reaction of the two components is virtually instantaneous. 1 2 345 Unique Production

15. Next Previous MOLD FILLING HistoryAdvanced Science The material is then injected into a glass mold. The design of the mold determines the format of the lens - semi-finished or finished, single vision or progressive, spherical or aspheric, etc. 12 3 45 Unique Production

16. Next Previous HEAT CURING HistoryAdvanced Science The molds are thermally cured in an oven for approximately 7-10 hours using a specified heat cycle ranging from 85°C to 130°C. During this step, the chemical reaction is driven to completion. 123 4 5 Unique Production

17. Next Previous DE-MOLDING HistoryAdvanced Science The lenses are removed from the molds and pass through an inspection process. Afterward, the lenses are packaged and delivered to optical laboratories and eye care professionals around the world. 1234 5 Unique Production

20. Next Previous The higher the Abbe value, the more accurately a lens aligns the spectrum of light waves that pass through it. Lens materials with lower Abbe Values are unable to focus these light waves accurately, resulting in "chromatic aberration," a vision defect that appears as distracting fringes of color around dark type and objects.

SPECIFIC GRAVITY: This number compares the relative density of an object to an equal volume of water. Anything with a specific gravity less than 1.0 will float. The lower the number, the lighter and, therefore, more comfortable the lens will be.
