The Hammond Optical PracticeRodenstock Colormatic photochromic lenses
Optimum protection, whatever lighting conditions you find yourself in.
They are almost clear indoors, but react quickly to up to 85% light absorption in the sun. The advanced plastic material is flexible, lightweight and durable, and offers full UV protection to 400nm in all stages of activation.
They are available in single vision, bifocal and varifocal/progressive lens forms - even in thinner, flatter high index and aspheric options.
