Application
This instrument is used to detect the impact resistance performance of glasses. The test method is to fix the glasses on the head mold or the lens fixed sample holder, and use the free fall of steel balls to impact the glasses to detect the rupture or shedding of the glasses due to the impact of external force to judge the safety of wearing.
