This lens comes as the standard low-light lens option for most Smith goggles that feature both a high and lower light lenses. Available in multiple colors, as well as, both mirrored and non-mirrored version, the Sensor series of lenses are very versatile. With a multi-layer, slightly mirrored coating, the sensor excels in flat lighting conditions where it optimizes both color definition and depth perception. Most models are rated at or near 70% VLT, with darker colors and mirrored versions having a slightly lower rating. This refers to the amount of light from the visible spectrum that is allowed to pass through the goggle lens.
