High stretch resistance(high impact resistance) : as it is
nano metal oxide lens, the stretch can be twice more than CR**9,
second only to PC lens 1.The
lens is made of the newest compound nano material ,which mixes nano
metal oxide and CR**9 together by applying national **3 program
technology. 2.The
world’s first , proprietary technology, appraised as international
advanced level by expert panel of Burea of Technology
3.The
lens uses international first-class nano material “nano mateal
oxide”,size at *0—*0nm
