Since 1984, Strike King has been a leader in polarized sunglasses for fisherman. These sunglasses include lenses made with APT (Advanced Polarization Technology). The benefits over traditional CAB plastic lenses are: greater visual acuity (improved contrast and sharpness), a more rigid lens and smooth "state of the art" coating creates greater resistance to scratches and hence better optical performance.
