Smith 4D MAG Replacement Lens

100% UVA/UVB Protection

BirdsEye Vision™ – Clarifies not just your line, but the riders in your periphery. The 4D MAG has a 25% increase of overall field of view compared to Smith's I/O MAG. Utilizing Smith's new BirdsEye Vision™, you can now see more than ever before.

ChromaPop™ Lens Technology – Through Smith's proprietary ChromaPop™ lens technology, we help you see detail and color beyond normal capabilities. ChromaPop™ filters two specific wavelengths of light that cause color confusion. By doing this the lens delivers greater definition, more natural color, and unmatched clarity to allow you to see more detail.

Tapered Lens Technology (TLT) – Visual distortion occurs when light waves hit an aggressively-curved lens causing it to bend or distort an object's true size or position. Tapered Lens Technology corrects the distortion by progressively tapering the lens from the optical center towards the outer edges. Light waves are thereby delivered straight to your eye resulting in zero distortion and true optical clarity. What you see is what you get. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.

5X™ Anti-Fog Inner Lens – The most advanced anti-fog lens ever created, engineered to provide over five times the absorptive properties of anything on the market.
