A minimal design is the framework of this lightweight performance sunglass, which serves up surprisingly high quality polarized optics for an affordable price. The optical clarity is derived from Zeal’s Hyperion lens technology. Looking for a balance between ballistic-grade technology and optical clarity, Zeal developed an injection-molded polycarbonate blend lens that is truly crisp and clear. It offers higher-than-required impact resistance and noticeable color perception.

The new lens also offers 100% UVA, UVB, and UVC protection plus glare-squashing polarization. The impressive optical package is even more remarkable when you consider its $139 pricepoint. There was little glare with this lens, even when running on the snow. There were, however, some reflections on the backside of the lens when running in a direction that was looking towards the sun. The reflections disappeared when looking away from the sun’s direction. This factor did cause some visual disturbance.

In terms of fit, the Zeal Equinox’s lightweight ProFlex Rubber temple tips are comfortable. The sunglass also features excellent nosepad adjustability, although the nose bridge became slightly uncomfortable when worn under a winter hat.

Zeal does strive for eco responsibility with its Z-Resin frame material, which is made of castor oil derived from castor beans. The entire line of Zeal sunglasses, including the Equinox, is manufactured with this material.
