Disadvantages of bifocal glasses
The disadvantage of bifocal glasses is that the different areas are clearly spaced and the appearance is not beautiful. The medium distance is fuzzy, and the adaptation period is needed, there is a prismatic jumping phenomenon. The focal distance between the upper and lower lenses is different, with a clear dividing line. The main disadvantage is that when the line of sight moves from far to near, there will be interference like jumping, and the middle distance object image is blurred. Students can adapt to sitting still in a class by wearing bifocal glasses, but they can only wear glasses when they are in class or studying because of the inconvenience and even danger caused by the interruption of the glasses.
Titanium is currently too expensive to refine.
It is highly demanding in buckling, stamping, cutting, and welding. The extraction of titanium, like that of aluminum before the 19th century, was quite costly and produced in limited quantities, so it was used only in extremely important fields, such as aerospace, electronics, precision instrument manufacturing, and so on.
Adjustment of the upper and lower position of the nose pad
The nose pad can be pulled up and down with the pliers of the nose pad to achieve the purpose. You can use needle-nose pliers to clamp on the nose pad and apply torque in a certain direction to change the upper and lower position of the nose pad. When applying the torque, the nose pad can be pressed down or pulled up by the pliers to change the position of the deformation of the bracket, to prevent repeated deformation and fracture near the solder joint.
