Endura Spectral, Cycling Sunglasses THERE ARE SEVEN kinds of Spectrum shades available from Endura but the most versatile is this blue lens version. They give a crisp increase in contrast for better depth perception in low light or hazy conditions, & yet they aren’t too bright when it’s sunny. You could also buy a clear or yellow pair for grim days, the blue for all-round use, & the Smoke lens for sunny days & still only spend £50. The arms can be bent into place for adjustment. For the money these are fantastic value performers.
