SPY yellow-blue spectra lens
I have decided on getting either the Smith Phenom goggles, or the Spy Soldier goggles. If I get the phenom, I plan to get the Sensor mirror lens for low light/ night riding. Which Spy lens compares to Smith's sensor mirror? I have searched everywhere and am under the impression that the Spy yellow-blue spectra lens is good for low light conditions. But I have also read that it is for very sunny conditions.
Could someone please tell me what conditions the yellow-blue spectra works in?
