Manufactured in the USA, Ops-Core Mk1 Performance Protective Eyewear was designed to meet the need for more ruggedized, mission configurable eye protection for the military and police. To deliver this solution, Gentex Corporation leveraged over 50 years of experience in high performance optics manufacturing, and the fundamental design principles of their Ops-Core® brand: modularity, scalability, and user-driven designs. Mk1 delivers eye protection in the toughest conditions, with durable aluminum metal frames that are available in a variety of colors and interchangeable lenses that give varying levels of protection (such as shooting eye protection or laser protection) based on specific threats and conditions. The frames can be formed for each user's perfect fit, ensuring stabilization during dynamic activities to provide eye protection when it is needed most. The user-based design of Mk1 eyewear is made to support a wide range of mission needs, always protecting the wearer's vision and helping enhance and maintain their operational performance. Mk1 functions as laser safety glasses, with optional Laser Dazzle lenses that protect against green and blue commercial lenses.
