Maui Jim is a recognized leader in sun protection technology. Their Polarized Plus and Polarized Plus 2 lenses block 100 percent of UV rays, and they “manage” blue light without interfering with color balance and perception. Maui Jim sunglasses are designed to compensate for all three types of glare: reflected, direct, and bounce-back. The Maui Jim polarized filters absorb 99.9 percent of reflected glare. The bi-gradient mirror coating mimics the effects of squinting, thereby minimizing direct glare. And the anti-reflective coating absorbs bounce-back glare, which is reflected from behind or to the sides.
