forming a microscope system to magnify the near distance objects even significantly, thus forming a telescope with high magnification to satisfy the needs of amblyopic groups, it can be used in the field of medical, biology, clock and watch, machinery, printing, and device Maintenance. it can also be used Help amblyopia people with observe far- and near-distance objects
  

Spectacle type bifocal monocular with 5 lenses comprises of a 2.5× monocular telescope visual aids on a spectacle frame. It is used for observation of far distance target. Additionally, 5 convex lens with different magnification (2×, 3×, 4×, 5×, 6×) can be placed in front of the monocular telescope, forming a microscope system to magnify the near distance objects even significantly, thus forming a telescope with high magnification to satisfy the needs of amblyopic groups.
