Alpinamente running sunglasses RARE

Whether you’re active and running across fields or hiking in the shade cast by mountains or walking in an urban scenery among skyscrapers or biking in a park, the light intensity might change frequently. Photochromic lenses darken automatically when exposed to sunlight and seamlessly adapt to the perfect shade under varying weather conditions. The photochromic sunglasses offer the optimal range between clear and dark transmittances for outdoor activities. In bright conditions, lens darkness will never compromise your vision and focus, for an optimal eyesight in action.
