Since an individual's scotopic (nighttime) vision is most sensitive in the shorter wavelengths (blue green), these bronze PilotShields lenses absorb the blues, thus allowing fast night vision adaptation after your PilotShields are removed at dusk. Also, fog consists of relatively large droplets which scatter all wavelenghts of light equally. Thus, there is no benefit to having tinted lenses in fog. But pilots are acutely aware of how visibility drops off when flying in a haze layer. The atmospheric haze is caused by smoke and other fine suspended particles. Unlike fog, haze causes small particle scatter which is wavelenghtdependent. The bronze PilotShields reduce unwanted scattered light from entering our eyes by absorbing shorter wavelength light, which is that light most scattered by small particles.

Comes with Pilotshields imprinted hardcase and cleaning cloth.
