The strehgth of tempered glass is several times greater than ordinary glass, bending strength is **5 times of ordinary glass, the impact strength is 5 to *0 times  of ordinary glass , improving the strength and security of glass lens.
      The safe in utilization is also an advantage of tempered glass. its carrying capacity is increased to improve the fragilenature , when tempered glass damaged, the glass lens will broke into obtuse debris, reducing damage to the human body greatly. the resistance to thermal temperatureshift of  tempered glass is 2 to 3 times improved  than ordinary glass, and can withstand temperature changes of more than **0LC,this give it a significant effect to prevent the heat burst.
