High-index 1.61 Free From Progressive Photochromic lenses : Progressive lenses are the closest to how natural vision is that you can get in a pair of prescription eyeglasses. They are more than just a defined near and distance correction in one lens. Rather, progressives provide a smooth transition from distance through intermediate to near, with all the in-between corrections included as well. This constant graduation of the prescription means that you can look up to see in the distance, look ahead to view your computer in the intermediate zone, and drop your gaze downward to read and do fine work comfortably close up. The difference between photochromic lenses and ordinary color lenses is that photochromic lenses can change from light to dark depending on the amount of ultra violet light. This feature offers great comfort to eyeglass wearers.Photochromic lenses come with built-in anti-scratch, and 100% UV protection.
