This is as good as driving specs get. The Serengetis deal with all weather conditions brilliantly in bright sunshine they reduce glare, and in fog or rain the clever filters block out blue light to improve visibility. We picked out the Navigator frame design because the large lens size helps stop unfiltered light creeping round the edges, but they are quite heavy and can feel uncomfortable when worn for hours on end.
You get what you pay for, as they say. We spotted a sizeable 33 discount at sunglasses-shop.co.uk (which includes free delivery and a leather-covered hard case), but these glasses are never going to be a budget buy.
Superb lens quality, with solid frames and hinges that look and feel as though they'll last. The lenses are made from glass, so they should resist scratching well, too, but we wouldn't advise dropping them on a hard surface!
The 'Espresso' drivers' lenses adjust to changing light conditions. Spectral control improves contrast and enhances the most important driving colours (that is, reds and greens for brake and traffic lights). One hundred per cent of UVA and UVB rays are filtered out as is 95% of blue light. This reduces the haze caused by spray and fog, and helps protect your eyes against macular degeneration. Prescription versions are also available at a hefty premium.
