6 Base Curvature - The base curvature corresponds to the curve of the lens. The higher the number, the higher the curve. 6 base styles have a “flatter” look. 8-9 base curves hug closer to the face.

Frame Material

eVolve Material - For more than 40 years Smith has been a steward of the outdoors. Great days in the water, dirt, and snow are made better when we protect the environment as well. By utilizing a new material called Rilsan Clear, they are creating lightweight, durable, and fully transparent sunglass frames that are over 53% bio-based.

Frame Tech

Adjustable Silicone Nose Pads - Tailor fit adjustable nose pads allow you to customize the fit and feel of these sunglasses.

Lens Tech

ChromaPop - By blocking color wave intersections as they pass through the lens ChromaPop is able to eliminate color confusion, enabling you to see the outside world with an unparalleled level of vibrancy.

Frame Measurements (mm)

These measurements include the width of the lens, the width of the bridge and the width of the arms/temples.

Extra Info

Pro Tip - Are polarized sunglasses better? Are they worth the price?

In many cases, yes. All sunglasses reduce brightness and block some amount of harmful UV rays. However, only polarized sunglasses are scientifically constructed to eliminate glare. Not just reduce it, but eliminate it. Fully polarized sunglasses reduce eye strain and help you see better around water, snow, sand or any other reflective surroundings.
