All Sunglasses

The best polarised sunglasses for driving use Polarised Polyfilter lenses, which cut reflected horizontal glare off the road and bonnet — the main cause of eye strain on long drives. Dirty Dog's Lifestyle range uses this lens technology as standard, paired with flexible Grilamide TR90 frames

It depends on the sport. For running and cycling, you want lightweight TR90 frames with rubber nose pads and temple tips for a non-slip fit. For water sports like surfing or boating, look for a Wetglass model with a hydrophobic coating that sheets water off the lens. Dirty Dog's Sport range covers both with shatterproof polycarbonate lenses as standard.

Yes — polarised lenses block the flat, horizontal glare that bounces off wet roads, bonnets and windscreens, which standard tinted lenses don't remove. This reduces eye strain and improves visual comfort, especially in low sun or wet conditions.

Not for oncoming headlights — polarised lenses target reflected glare off flat surfaces like wet roads, not direct light sources. Dirty Dog doesn't recommend any tinted lens for night driving; Protection Index 4 lenses are explicitly unsuitable for driving at any time.
