Vision Concept - More than anything , good running eyewear must ensure good
vision. Glare, weak light or light fluctuation from bright to full can impair
sight. adidas eyewear lenses meet the criteria of optical quality class 1.
From the adidas Auckland Marathon to the Kepler Challenge or the Southland
Half Ironman then good eyeewear helps prevent rapid eye fatigue, boost
concentration and reduce the risk of injury.
