Strike King Tiger Shiny Black Bait (Blue Mirror, Adult) The Strike King Black Tiger Sunglasses feature shiny black frame and gray blue mirror lens, rubber vented nose piece, and soft, nonslip temple inserts. Since 1984 Strike King has been a leader in polarized sunglasses for fishermen. New models include lenses made with APT Advanced Polarization Technology. The benefits over traditional CAB plastic lenses are: greater visual acuity (imporved contract and shapness), a more rigid lens and smooth "state of the art" coating creates greater resistance to scratches and hence better optical performance. Polarization in fishermen's sunglasses is a must and a benefit for most all other uses and all Strike King models are polarized.
