 Our polarised clip on sunglasses have been tested and approved for driving, and meet British and European standards recognition of traffic signal lights and colours.
We have 3 polarised lens colours that are optimised for use in different light conditions: grey, copper, and yellow.
The polarising lenses act like a microscopic venetian blind to reduce the sun’s glare by up to 99.97%. This is particularly important when driving where reflected glare from road surfaces and car bonnets can be a severe hazard and cause eye fatigue.
It is important to observe our safety guidelines when using clip on sunglasses for driving and never use them for driving at night.
 Driving in very bright conditions
For driving in bright, sunny conditions where intense reflected sunlight is a problem, use the polarized smoke grey lenses. They are designed for intensive sunlight conditions. Their low visible transmittance, combined with 99% polarizer efficiency, provide maximum protection against the sun.
The grey lenses reduce light intensity, while maintaining original colour, with no distortion. They relieve glare and increase contrast.
 Driving in moderate sun and variable conditions
Copper is good for driving in variable light conditions because the lenses offer the best compromise between visible light transmittance, blue light absorption and a high red factor.
This results in enhanced reds such as traffic lights and car brake lights. The lenses enhance colour contrast sensitivity and give you a sharper image under hazy weather conditions. Because our lenses our polarized, they significantly reduce the sun’s glare.
 Winter driving in hazy and misty conditions
Yellow polarized clip on lenses are an excellent choice for winter driving. The yellow filter gives you sharper vision in misty, rainy or dull conditions, while the polarization virtually eliminates the glare from low angle sun or car headlights.
Additionally, the lenses benefit from a flash-mirrored front surface, and an anti-reflective back surface that makes them more comfortable to wear, by reducing reflections of light from behind you that bounce off the surface into your eyes.
Note: these lenses are not recommended for night driving.
