Make:Specialized 'Miura' Price: £84.15 From: Cyclestore March '08 In Spring and Autumn I commute 'into the sun' - it makes for a variety of light conditions and, coupled with the shadows cast from buildings along the way, makes for a complicated view! The rest of the time they are for road use. I have all sorts of interchangeables, fixed density sunglasses etc - chopping and changing was not practical in heavy commuter traffic. To alleviate this, I chose a brand of sunglasses that might help me deal with these extremes (helpful comment was given elswhere and I already had an idea of which mark I was going for...). I hadn't anticipated parting company with so much dosh but I can honestly say they are a class apart from anything else I have worn. So far they have dealt with every condition (without steaming up!) day and night (the pink lenses accentuate reds ie: warning lights etc). I hope they last me a long time. Oh - and they are designed as a 'large frame' for those with a er 'large frame' for the contents of their head!
