Spectacle-type bifocal monocular with 5 lenses C-8541
forming a microscope system to magnify the near distant objects significantly, thus forming a telescope with high magnification to satisfy the needs of amblyopic groups, it can be used in the fields of medical, biology, clock and watch, machinery, printing, and device Maintenance. it can also be used to help amblyopia people observing far- and near-distance objects
  

Spectacle-type bifocal monocular with 5 lenses comprises a 2.5× monocular telescope visual aids on a spectacle frame. It is used for the observation of far-distance targets. Additionally, 5 convex lenses with different magnifications (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.
