I always wore Raybans, tried Oakleys and various other types at various times, then just a few years before I retired I discovered Serengetti Velocity sunglasses with titanium frames and drivers gradient lenses and wished I'd found them 20 years before. When my original pair were stolen I went straight out and bought an identical pair. I had a look in Sunglass hut today and they still sell them there. They're not cheap, but worth every penny in my opinion.
