Optima has released a new polarized 1.60-index aspheric plastic lens—called PolarTec—it hails as the “darkest lens on the market.” Like most polarized lenses, it is designed to reduce glare and eyestrain. The first 1.60-index plastic polarized lens on the market, according to Optima, PolarTec offers 100 percent UV absorption at 390 nanometers. The company also bills it as the “darkest” polarized lens on the market. POLARTEC can be surfaced to a 1.5mm center thickness. “Optima’s newest product, PolarTec, is another innovation in a long line of industry firsts,” says Nicholas Niejelow, president of Optima. “PolarTec, the first and only 1.60 polarized lens, is the thinnest and darkest available. Once again Optima has set a new standard of excellence.”
