Smith Touchstone Polarchromic Sunglasses

Smith Touchstone Polarchromic Sunglasses

A new level of comfort and visual performance has been achieved. The Touchstone showcases all of our finest technology and features. Refined surfaces and detailing combine with maximum coverage, a secure fit, and strong styling.

Smith Polarchromic lenses combine the glare-free benefits of advanced polarization with UV sensitive, self-tint-adjusting photochromic technology to bring you the most advanced sunglass lenses Smith have ever created.

How do they do it? Precise amounts of silver halide crystals are infused into the glass lens material during their creation. These microscopic crystals automatically change orientation in response to UV light which results in a shift in tint either increasing or decreasing Visible Light Transmission (VLT), fine tuning the tint of your lens in response to ambient light conditions as they change throughout the day.

Smith Polarchromic never wears out or gets tired lasting the life of the your sunglasses. The result? You get a lens which offers crisp optics and soothing light levels at all hours allowing you to focus on what matters most from dawn to dusk.
