These are clip-on polarized lenses that turn a pair of readers into sunglasses without swapping frames. The TAC lenses carry UV400 protection and cut glare from roads, water and other bright surfaces, which is the main reason people buy them. The 54 × 34 mm lens size gives wide coverage, and a spring draw bar holds the clip in place on compatible frames. They suit anyone who wears readers outdoors and wants one pair to do both jobs, though they only work on frames whose shape and size match the clip.
