The Radar is a development of the classic M-Frame. It's more casual in appearance, but still very obviously a sport shade.
It’s hard to fault the ﬁt – two different width nose bridges are supplied and you can pick from three sizes of lens – and Oakley’s hydrophobic lenses are nigh-on unbreakable, offer excellent coverage and no distortion.
Our pictured pair look odd because they have prescription lenses bonded to them (prescription Radars start at £225). While expensive, Oakley prescription sports shades are probably the best you can get.
