lens type - / lenz taɪp / -
noun
Different shades of lens on snow goggles, designed to optimise riders vision depending on weather conditions. A darker lens, towards the grey end of the colour spectrum will perform better in brighter light conditions, whereas a yellow lens will perform in lower light conditions. Higher end goggles tend to come with an interchangeable lens system, so these can be easily swapped on the mountain depending on the conditions. Manufacturers continue to develop lenses that are designed to work more effectively across a wider spectrum of light.
\\ I wish I'd brought my yellow lenses today, they're the only lens type that lets me see anything in these conditions.
