This week I was given the opportunity to try two more Peak Vision Sports models: the XR4 and the XK5. These two new products do, in my opinion, represent a significant improvement over the good old SL8 – they both feature the well-tried Dual Zone lens and new one-piece, shield style lenses designed to provide unobstructed vision – and remove that sometimes annoying, and often distracting, central ghostly shadow of the nose bridge.
But more than all that, these two new products (and the SL8) not only shield the eyes from the harmful rays of the sun, they do seemingly without any loss of light at all. I can even read a book while wearing them, something I could never do with any other brand of sunglasses.
