The flexible, strong plastic frame is light and doesn’t intrude on vision. The lens shape is great, sitting close to your face and with no annoying reflections. They’re well-ventilated, with gaps along the tops of the lenses, and we didn’t have any issues with them steaming up.
The nosepad is adjustable to give a good fit, and rubber hydrophilic arms keep them in place. The lens we tested is dark and mirrored, best for only the brightest days, but you can buy different options. Vision quality was fine rather than brilliant, but there’s no distortion from the shape of the lens. They’re a brilliant price for decent sports sunnies.
