Features 

Vivid
Vivid is a patented lens technology, developed by Giro in partnership with ZEISS Optics – that improves the visual experience on snow by enhancing contrast and definition. VIVID Lens Technology effectively manipulates blue light by letting in contrast enhancing blue light, while blocking harmful UV light. VIVID essentially filters out the haze and frees your eyes to spot your line and focus on enjoying your riding experience.

Evak
Found exclusively on Vivid goggle models, Evak Vent Technology uses a new foam made from an ultra-durable, non-absorbent material. Evak vents minimize the chance of fogging by releasing moisture while simultaneously creating a barrier from the elements.

VLT
Each lens has a Visual Light Transmission, percentage unit that describes how much light the lens will allow through to your eyes. The higher the VLT percentage, the more light goes through (great for dark conditions), the lower the percentage the less light goes through (great for bright conditions).
