Copper lenses provide sharper contrast and image definition by filtering 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. Yellow lenses are commonly used by drivers for their excellent contrast enhancement and depth perception properties. They're especially effective in flat light or overcast conditions helping to increase visibility. With a luminous transmittance of 82% they're also suitable for use as night driving glasses.
These driving fit-over sunglasses are available with either glare blocking polarised lenses for improved optical quality or shatterproof polycarbonate lenses (PC) which may be required for use with some digital instrumentation.
