For people who need to wear glasses, glasses are really a very important thing. When they don’t have glasses, the beautiful scenery in front of them becomes a gray and blurry scene, and they can’t know the real face of the person on the opposite side, and they can’t appreciate the beauty of the glasses scenery.

So glasses are invaluable for those who need them. Does each pair of glasses need to be torque tested during production? Of course needed.
