Visor tint: Dark smoke, Mirror, & Multi-layer visors all have the same amount of darkness and can be compared to a pair of Oakleys Photochromic Visors: Photochromic visors automatically darken when exposed to sunlight, similar to transition lenses. Mirror Visors: Mirrored visors are highly reflective (like a mirror) there is a substantial color shift depending on the angle at which you view them. This does not apply to silver mirror. Multi-layer Visors: Multi-layer visors offer a deeper, richer color. They have less color shift and are more consistently a solid color. Peak Visor: Perfect for drivers who want the openness of an open-face and sun protection. Great for rally drivers as well.
