Driving
Driving clip-on sunglasses with copper driver lenses provide sharper contrast and image definition by blocking blue light and reducing road glare whilst preserving a natural colour balance for comfortable viewing in the day light. Driver lenses relax the eye muscles to reduce stress whilst driving and are designed to highlight the critical driving colours, i.e. red, amber and green. They're available with either glare blocking polarised lenses for improved optical quality or non-polarised shatterproof lenses which may be required for use with some digital instrumentation.
