In 1985, optical engineer Dr. Mitch Ruda, working on a project for NASA, made a breakthrough discovery: using the protective coatings of satellites to defend the eyes from sunlight. This insight gave birth to Revo. The MERIDIAN model has a rectangular shape that combines style and performance technology. Made from a single sheet of titanium, with flexible beta-titanium front and temples. The lightweight, curved design provides full coverage from rays from all angles. Next-generation Revo polarized lens technology adapts to changes in light. DETAILSPRODUCT:Gender: UnisexShape: RectangularMaterial: TitaniumColor: 01gy BlackCaliber: 58Bridge: 17Rod: 135
