GUNNAR lenses are comprised of a proprietary lens material in an advanced geometry tuned for specific viewing distances and finished with custom formulated lens tints and coatings. GUNNAR eyewear delivers an immediate and noticeable visual advantage in the short term, and provides superior optical performance in the long term. Finished to exacting specifications and machine polished with high velocity micro particulates, the engineering behind PHENOM is only outdone by one thing. its artistic style. Micro-engineered lenslocks add both flexibility and flair. An exercise in creative contrast.
