The Zeal Optics Emit Polarized Sunglasses may have an oversized, wrap-around lens, but that doesnt mean youll look like you just donned Robocops head shield when you wear em. Although these shades do give you ridiculous peripheral coverage, the Emits also have a sleek, clean-line design. Zeal Optics uses ZB-13 polarized technology which cuts glare in a broad range of light conditions. This means the Emit Sunglasses are equally useful on super sunny days and under bright white skies. Non-slip nose and temple pads keep these shades on your face during sweaty bike and boat rides.
