Blue Mirror Glass: I would use the blue mirror for cloudy days and high glare. The blue mirror lens still gives you good depth of perception, but the mirror deflects all the glare. It is an excellent all-round lens for use in both shaded, muddy and medium light, sunny / cloudy conditions. Your view through the blue mirror lens will appear pale yellow.
