C-Spec Performance series features 12 distinct choices optimized for three main light conditions. Every C-SPEC performance series lens features a respective fade and/or mirror finish, anti-glare coating, light condition identifier, and thermal dual pane anti-vapor inner seal.
Highlight (HL) Series lens options are designed for use in bright and direct sunlight and provide the lowest light transmission to your vision. HL lenses minimize glare by decreasing white balance and sharpening contrast. Performance HL lens options feature injected tint and a mirror coating with a low Variable Light Transmission (VLT%).
