Silhouette Minimal Art - the lightest glasses I've ever worn, bendy titanium arms; comfortable for hours under a headset. Available in all flavours of prescription, non-prescription, sunglasses, polarised, non-polarised and even quite trendy too.
I have the non-polarised sunglasses (non-prescription) and they were £120. They are so comfortable I hardly ever wear my Oakleys or RayBans any more.
