Study Notes

Frame Standard Alignment and Repairs

  • The chapter reviews frame manipulation, tools, and techniques, covering various types of pliers and soldering procedures.
  • Frame materials such as plastics and metals have different manipulation requirements
  • Nylon jaw pliers are used for frame adjustments, particularly for rimless frames
  • Angling pliers are used to adjust the angle of side tilts and temple folding angles
  • Pad adjusting pliers are designed to adjust nose pad splay angles
  • Finger piece pliers manipulate the angle of sides, hinge screws, and end-pieces
  • Square/round pliers adjust coplanar lenses (x-ing), side tilts, and folding angles
  • Standard Alignment is the process of manipulating frames to a predetermined shape established by the manufacturer. It is typically done by the frame manufacturer initially and the lens laboratory after lens fitting
  • Standard alignment procedure steps include checking the contour of the frame front, ensuring lenses are in the same plane, checking temple angles, checking that the temples are in the same plane, checking the angles of the temple ends and ensuring the frame conforms to a flat surface.
  • Soldering involves melting a soft metal to join two metal parts
  • Resinking a joint involves heating the joint and inserting it into the plastic frame.
  • Repairing the bridge (acetate) involves drilling holes, cutting wire, placing the bridge in acetone, and holding it in place.

Importance of Standard Alignment

  • Ensures quick and precise adjustments to the patient's features
  • Should be checked before delivering the spectacles to the patient

Limitations of Repairs

  • Repaired frames are not as strong as original frames, especially the bridge area
  • Bridge repairs and soldering to metal frames are considered a temporary solution.
